1500622 - fix WPT grid-positioned-items-implicit-grid-line-001.html to comply with Grid spec

Status: NEW

(Core :: Layout: Grid, enhancement, P5)

Description

[Mats Palmgren (inactive)]

This WPT is bogus after the spec change we implemented in bug 1490730:
testing/web-platform/tests/css/css-grid/abspos/grid-positioned-items-implicit-grid-line-001.html
We should update this test and upstream it.

WPT.fyi page for this test https://wpt.fyi/results/css/css-grid/abspos/grid-positioned-items-implicit-grid-line-001.html?label=master&label=experimental&aligned

Mats, would you mind checking whether our two failures there are due to this bug? (I assume/suspect they would be.) Notably, Chrome and Safari both pass these tests -- so if our behavior is in fact correct, then this might indicate a bug in their implementations (e.g. maybe they never implemented bug 1490730 themselves).

mats, just wanted to be sure you saw the ni poke -- we should either fix this test ourselves, or tag rego to do so, or get it removed from the compat2021 test set, given that it has incorrect expectations (assuming it's still incorrect).

Clear a needinfo that is pending on an inactive user.

Inactive users most likely will not respond; if the missing information is essential and cannot be collected another way, the bug maybe should be closed as INCOMPLETE.
