[cssom-view] Specify document.caretRangeFromPoint? #6459
Description
Per MDN it has been supported in Chrome and Safari for many years. While there is an alternative, I guess it should probably be in spec for web compatibility, although I haven't investigated its impact.

@foolip I see your comment in that mailing list. Per https://www.chromestatus.com/metrics/feature/timeline/popularity/387 the use count is 0.2% which is big enough and I doubt
caretPositionFromPointhave lower use count given that it also has been there for years. What do you think, should we specify both?caretRangeFromPointreturn type should beRange | nullmicrosoft/TypeScript-DOM-lib-generator#1072saschanaz commentedon Jul 17, 2021
Oh, just found that
caretPositionFromPointis currently Firefox only, I guess it also needs a use counter then.saschanaz commentedon Jul 17, 2021
The WebKit implementation simply wraps
caretPositionFromPoint, which has never been exposed...foolip commentedon Jul 20, 2021
It seems like the current situation is that Chromium and WebKit have
caretRangeFromPointwhile Gecko hascaretPositionFromPoint.Spec'ing
caretRangeFromPointandcaretPositionFromPointone in terms of the other in a way that would be trivial for all engines to support sounds like the best path forward to me.There is a risk that these methods are used for UA detection, but other than that I don't see other risks.
