Rationale

Over the last 1-2 years we've slowly added test-cases to the suites from bug reports we've received[1], or spec clarifications/behaviour changes[2].

Additionally this is updated for the "last baseline" alignment feature which all engines have basic support for now.

I'm not sure there's a well defined process here; we (with agreement) accept updates to the 2022 testsuites, but generally adding scope for a subsequent year should be in the context of a new focus area.

If there are areas where bugs are showing up as site breakage or compat problems, the tests might be suitable for the web compatibility focus area.

Self-assigning to label the tests with a temporary label to show what the impact on the scores would be.

I'm going through and labeling with interop-2021-flexbox-expansion and interop-2021-grid-expansion. I see there are some tentative tests, and I'm not labeling those:
https://wpt.fyi/results/css/css-flexbox/alignment/flex-align-baseline-line-clamp-001.tentative.html
https://wpt.fyi/results/css/css-flexbox/alignment/flex-align-baseline-line-clamp-002.tentative.html
https://wpt.fyi/results/css/css-flexbox/alignment/flex-align-baseline-line-clamp-003.tentative.html

[foolip]

I also won't label anything names -print or -crash.

[bfgeek]

You likely want to keep those tentative tests, they just need spec text surrounding them..

[foolip]

@bfgeek do you know which spec issue those tests depend on? (Nothing is linked from the tests.)

Here are views of the existing + proposed tests:

• Flexbox
• Grid

[jgraham]

@emilio @dholbert do these tests look reasonable to include in Interop going forward.

[foolip]

Thank you for proposing updated grid/flex tests for inclusion in Interop 2023.

We are pleased to let you know that this proposal was accepted as part of the existing Flexbox and Grid focus areas. You can follow the progress of these Focus Areas on the Interop 2023 dashboard.

For an overview of our process, see the proposal selection summary. Thank you for contributing to Interop 2023!
