a8d93986f4 Fix serialization and mutation of <textarea> elements (#1351)
* 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

d1d0c7f366 Masking: Avoid the repeated calls to closest when recursing through the DOM (#1349)
* masking performance: avoid the repeated calls to `closest` when recursing through the DOM
 - needsMask===true means that an ancestor has tested positively for masking, and so this node and all descendents should be masked
 - needsMask===false means that no ancestors have tested positively for masking, we should check each node encountered
 - needsMask===undefined means that we don't know whether ancestors are masked or not (e.g. after a mutation) and should look up the tree
* Add tests including an explicit characterData mutation tests 
* Further performance improvement: avoid calls to `el.matches` when on a leaf node, e.g. a `<br/>`

* 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

* Perf: If parents where already checked, no need to do it again

* Perf: reverse for loops are faster

* Revert back to puppeteer 9.1.1

* Keep index order consistent between replay and record

* keep correct index order in webgl2

* fixed forgotten import

* buffer up pending canvas mutations

* unify the way webgl and webgl2 get patched

* fix parsing error

* Add types for serialize-args

* Add debugging for webgl replay

* Move start-server to utils

* turn off debug mode by default

* Move pendingCanvasMutations to local object and fix if/else statement

* Always save pending mutations

* only use assert snapshot as it's clearer whats going on

* Ugly fix for now

* Making the tests more DRY

* flush at the end of each request animation frame

* Looks like the promise made this test more predictable

* add waitForRAF

* Make nested iframe recording robust no matter the test speed

* mute noisy error in test

* force a requestAnimationFrame

* Bundle events within one frame together as much as possible

WebGL events need to be bundled together as much as possible so they don't accidentally get split over multiple animation frames.

 `newFrame: true` is used to indicate the start of an new animation frame in the recording, and that the event shouldn't be bundled with the previous events.

* Rename RafStamps

* Override event.delay

* cleanup

* Add tests for addDelay

* Add webgl e2e test

* Remove settimeout

* DRY-up test

* Preload images in webgl

* Add e2e test for webgl image preloading

* don't turn on devtools by default!

* Remove spector

* close server after use

* Add imageMap parameter

* Make e2e image test more robust

* document debug mode

* cleanup

* WebGL recording in iframes & Safari 14 support

* fix tests

* don't save null objects as WebGLVar

* group (de)serialized webgl variables by context

* Fix test

* fix tests

* bundle webgl mutations on request animation frame

Instead of fixing it on the replay side we buffer up webgl canvas mutations and wait for a new RAF to flush them. This allows us to remove `newFrame` from the events and simplify things a little

* Add canvas element to mutation observer file

* Add Canvas (Mutation) Manager

Allows you to do `record.freezePage()` and canvas events will get paused.

* cleanup

* Make sure the correct </body> gets replaced
