IntersectionObserver's delay/trackVisibility and IntersectionObserverEntry's isVisible missing from main spec #468

Open foolip opened 3 years ago

foolip commented 3 years ago

https://w3c.github.io/IntersectionObserver/v2/ has a number of additions compared to https://w3c.github.io/IntersectionObserver/ which are shipped in at least some browsers, but https://w3c.github.io/IntersectionObserver/ (and https://www.w3.org/TR/intersection-observer/) are much more discoverable.

Is it time to promote https://w3c.github.io/IntersectionObserver/ to v2 so that the most up-to-date spec is more easily found?

Background: I was here to file issues about certain attributes not being in the spec, and found the v2 spec only after reading through Intent to Ship: IntersectionObserver V2.

Hmm, but looking at https://w3c.github.io/IntersectionObserver/v2/#idl-index and the date, it seems like v2 isn't the version of the spec being maintained.

For clarity, members that are missing from https://w3c.github.io/IntersectionObserver/ are IntersectionObserver.prototype.delay, IntersectionObserver.prototype.trackVisibility and IntersectionObserverEntry.prototype.isVisible. I'll rename the issue to make it clear that's the point of this.

"Shipped in at least some browsers" seems to be just Blink.

I haven’t found the place where these things were even proposed to other browsers. Looks like we need to re-start the process for these.

What's the status of this?

The TAG and Mozilla were made aware of this proposal here: https://github.com/mozilla/standards-positions/issues/109 https://github.com/w3ctag/design-reviews/issues/328

https://github.com/WebKit/standards-positions did not exist at the time.

The feature is used by over 6% of Chrome page loads by now: https://chromestatus.com/metrics/feature/timeline/popularity/3051

https://github.com/w3c/IntersectionObserver/pull/523 seems to be addressing this FTR
