* Replace relative URLs with absolute URLs when stringifying stylesheets
* Add test to show desired behavior for imported stylesheets from seperate directory
* Rename `absoluteToStylesheet` to `absolutifyURLs` and call it once after stringifying imported stylesheet
* Don't create the intermediary array of the spread operator
* Formalize that `stringifyRule` should expect a sheet href
* Ensure a <style> element can also import and gets it's url absolutized
* Handle case where non imported stylesheet has relative urls that need to be absolutified
* Clarify in test files where jpegs are expected to appear in absolutified urls
* Move absolutifyURLs call for import rules out of trycatch
* Add a benchmarking test for stringifyStylesheet
* Avoid the duplication on how to fall back

Setting of the `crossorigin` attribute is not necessary for same-origin images, and causes an immediate image reload (albeit from cache) necessitating the use of a load event listener which subsequently mutates the snapshot. This change allows us to avoid the mutation of the snapshot for the same-origin case.
* Modify inlineImages test to remove delay and show that we can inline images without mutation
* Add an explicit test for when the `image.crossOrigin = 'anonymous';` method is necessary. Uses a combination of about:blank and our test server to simulate a cross-origin context
* Other test changes: there were some spurious rrweb mutations being generated by the addition of the crossorigin attribute that are now elimnated from the rrweb/__snapshots__/integration.test.ts.snap after this PR - this is good
* Fix serialization and mutation of <textarea> elements taking account the duality that the value can be set in either the child node, or in the value _parameter_ (not attribute)
* Backwards compatibility: Bug fix and regression test for #112
- this is to fix up 'historical' recordings, as duplicate textarea content should no longer be being created at record time
- new test shows what the snapshot generated by previous versions of rrweb used to look like, hence 'bad'
- original 0efe23f04a fix either didn't work or no longer works due to childNodes being appended subsequent to this part of the code
- during review, we also verified that the `_cssText` case should still be handled okay, as there's currently no scenario where csstext is present with css child nodes of a <style>
* Masking: Fix that textarea values were being missed by the masking system if the value was recorded as a child node
- I didn't notice that form.html was used in other tests, so lucky that I noticed that those tests also should have the 'pre value' masked out
* Simplify by always storing the textarea value in the `.value` attribute (from it's DOM property) and not as a childNode. It should still be rebuilt as a childNode rather than a property

* feat: Ignore `autoplay` attribute on video/auto elements
This element leads to weird issues when replaying, so it's better to strip this out.

We were only excluding `<link rel="preload" as="script" />` but we should include `rel="modulepreload"` as well

* Record iframe mutations cross page
* Test: should record images inside iframe with blob url after iframe was reloaded
* Handle negative ids in rrdom correctly
When iframes get inserted they create untracked elements, both on the dom and rrdom side.
Because they are untracked they generate negative numbers when fetching the id from mirror.
This creates a problem when comparing and fetching ids across mirrors.
This commit tries to get away from using negative ids as much as possible in rrdom's comparisons
* Update packages/rrdom/src/diff.ts

* Implemented image restore from rr_dataURL
* Implement saving images in the snapshot
* Fixed image saving, added a test
* Rename data-src to data-rrweb-src
* Updated the guide
* Rename recordImages to inlineImages and try catch
* Hygiene: clean up the xhtml namespace attribute; this is an artefact of the `serializeToString` method which we are using (I think) to be consistent with whitespace and to clean up invalid attributes. I'm removing as was confused as am adding tests related to doctypes
* Record when a document is in `compatMode` and trigger this mode on the iframe upon replay
https://developer.mozilla.org/en-US/docs/Web/API/Document/compatMode
the included DOCTYPE was picked up from https://stackoverflow.com/questions/18976213/ - there may be better ways of triggering compatMode
* Don't write an extra DOCTYPE if there's one already present in the snapshot. Rely instead on whatever doctype is there to trigger the BackCompat mode
* Modify to write the correct doctype if we can sniff xhtml - don't have any evidence that this will make a difference
* Dev convenience: Ignore files generated by editors
* Typo fix
* Was getting a 2000ms timeout on the 'before' hook I believe
* Change certain tests to go directly to their localhost page instead of loading the html content programmatically in order to avoid triggering an incorrect BackCompat mode (incorrect in that the html content has a correct doctype)
* Add test based on motivating site that had images lined up in a square which were all different sizes; very old style percentage width/height attributes were doing the right thing in quirksmode, which is what we are testing for here
* Fixup rrweb test html to include a valid doctype and avoid BackCompat to ensure we're not accidentally testing against quirks modes. I didn't find an elegant way of avoiding the `BackCompat` when adding a minimal iframe, so some BackCompat has slipped in here, I don't think there's much harm
