* 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

* 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/>`

* only call createHTMLDocument where it is needed
* Perf: create the mutation document once as a 'singleton' as it can be reused

* Add config option to turn off all snapshotting and related observers
- allows RRWEB to be used for click/movement tracking alone, e.g. for a heatmaps use case
- could also be used if there was a separate process for recording the DOM (in which case a 3rd party library like https://github.com/antonmedv/finder could be added to record targets instead of the mirror)

* Perf: don't run the regex replace unless the selectorText contains a colon (rules generally contain colons)
* Need to check type before querying selectorText property - also good as it means we only try to fix colons at the leaf level

* Add a test which demonstrates how no mutations are generated when an element is created & destroyed in the same 'cycle' (a cylce here being enforced by freezePage)
* Test demonstrating current behaviour I'm about to modify; the data-test="x" attribute is present twice in the mutation, as is the textContent value of 'y'
* Attribute or text modifications on just-added nodes are redundant as demonstrated in test case
* Some correct test changes from other tests; I've manually inspected each of these mutation removals and confirmed that the attribute values are already present in the newly added nodes elsewhere in the same mutation
* Improve reliability of test case as per Justin's advice
* Don't use the CSSOM when there's `var()` present as it fails badly https://github.com/rrweb-io/rrweb/pull/1246
* As the CSS Object Model expands out shorthand properties, do a check on the string length before choosing which format to go for
- this approach allows 'var()' in a styleOMValue as it's only a problem when combined with a shorthand property
- before this change background:black; was getting expaned to 10 OM properties as follows:
'style': {
'background-color': 'black',
'background-image': false,
'background-position-x': false,
'background-position-y': false,
'background-size': false,
'background-repeat-x': false,
'background-repeat-y': false,
'background-attachment': false,
'background-origin': false,
'background-clip': false

* fix: rrdom bug
1. fix one bug of the diff algorithm
2. omit srcdoc attribute of iframe
* use linked list to iterate children
* fix the bug that the children of shadowRoot don't get diffed
* add test cases
* add change log
* Fix for #816 - avoid triggering a CSP (content security policy) error with `.setAttribute('style')`
* The bare unattachedDoc that I previously naively created didn't have a doctype and wasn't a HTML document, so the child style element didn't have the `old.style` attribute available
* Add a try/catch to provide some robustness in case `document.implementation.createHTMLDocument` isn't available
