[WebAPI] ship beforeinput event and InputEvent.getTargetRanges()

[chrisdavidmills]

Acceptance criteria

1. • The listed features are documented sufficiently on MDN
2. • BCD is updated
3. • Interactive example and data repos are updated if appropriate
4. • The content has been reviewed as needed

Features to document

1. beforeinput event and InputEvent.getTargetRanges()

Related Gecko bugs

1. • [UI Events][Input Events] Ship beforeinput event and InputEvent.getTargetRanges() in Release channel and Beta channel

We've already got these documented, so should be easy — BCD update, rel note, possibly remove experimental features entry?

For folks helping with Firefox-related documentation features — make sure above AC have been done, but also:

• Set bugs to dev-doc-complete
• Add entry to Firefox release notes if feature is enabled in release
• Add entry to Firefox experimental features page if feature is not yet enabled in release

Personal todo:

• Check docs
• BCD
• Release notes

Ha - so... I have BCD all ready to go, however this is still behind the pref for me in both 87 & 88. Have I misunderstood and it's still behind a pref, it will just be released in 87?

Both https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement/beforeinput_event and https://developer.mozilla.org/en-US/docs/Web/API/InputEvent/getTargetRanges are up to date.

BCD is up to date

I'm not sure what this means in regards to both BCD and release notes @chrisdavidmills -> I'm going to add to release notes as per comments here https://bugzilla.mozilla.org/show_bug.cgi?id=1665530#c7

Removed from experimental and added to release - plus a sentence as per above comment:

#2939

Hi @Rumyra ! Finally getting round to doing my reviews of this stuff.

On this one, I noticed that the BCD hasn't been updated. Since it is shipped in 87, both data points should be updated. Can you do that asap please? Thanks!

[Rumyra]

So sorry @chrisdavidmills !

See mdn/browser-compat-data#9481

No worries! Now we've got the BCD in, we can close...
