Remove css-scroll-snap/capturing-snap-positions.html

[nt1m]

** Test List **

• css-scroll-snap/capturing-snap-positions.html

** Rationale **

@nmoucht investigated this, and found this is testing an "at-risk" feature of css-scroll-snap, see: w3c/csswg-drafts#4496

It's also worth noting this is failing in all 3 browsers.

@flackr WDYT?

Thanks Botond for CCing me. Honestly I wasn't aware of w3c/csswg-drafts#4496 at all. In fact the situation in Gecko is pretty much same as what Majido mentioned in w3c/csswg-drafts#4496 (comment) . We don't care non scroll containers at all as of now, Handling non scroll containers wouldn't be too hard in Gecko, but I am not a big fan of it. I wonder web developers can intuitively understand the scroll-snap-type property behavior for such cases.

Anyway though I don't quite understand what the expected outcomes of the interop 2022 tasks are, dropping the test sounds reasonable to me.

@flackr Hi! Have you had a chance to look at this?

[flackr]

This is a tricky one. It's at risk and not implemented by any browsers so on track for removal, but it is still in the spec and in w3c/csswg-drafts#4496 there were good arguments for this feature making scroll snap more ergonomic, being relatively straigtforward to implement, and the plan is to revisit its removal after the rest of the spec is implemented. I do not think it makes sense to remove the test so long as it is still "planned" - perhaps rename it to be a tentative test instead to reflect its current at risk position?

@flackr Thanks for taking a look! If it's a tentative test, I think we should at least exclude it from Interop 2022 (not necessarily remove the test from WPT).

@foolip It seems like there's general agreement to remove it from Interop, should I (or you) move forward with the change?

[foolip]

@nt1m sorry for the delay, I'll remove the label now.
