https://wpt.fyi/results/css/css-flexbox/flexbox-align-self-baseline-horiz-008.xhtml?label=experimental&label=master&product=chrome&product=firefox&product=safari&aligned&view=subtest

Rationale

Relies on having implemented writing-mode: sideways-rl;, a feature that neither Webkit nor Blink have shipped, and isn't part of Interop 2023.

@jgraham can you review this for Gecko?

@gsnedders @nt1m can you review this for WebKit?

[nt1m]

Is it possible to replace with vertical-lr/rl? or is that already covered by another test?

But yeah, I agree we shouldn't have tests relying on sideways WM for Interop 2023

[davidsgrogan]

That's kind of covered by http://wpt.live/css/css-flexbox/flexbox-align-self-baseline-horiz-006.xhtml . I say "kind of" because 006 is about orthogonal children, not where the whole container is in a vertical writing mode.

Other than that, there isn't a straight translation of flexbox-align-self-baseline-horiz-008.xhtml for vertical writing modes.

Switching to vertical writing mode SGTM.

@davidsgrogan is the conclusion to update this test instead of removing it?

[davidsgrogan]

Sorry, I'm new to the process... does the process require input from all 3 engines before there can BE a conclusion? (Haven't heard from gecko yet.)

[bfgeek]

This test should just be excluded rather than changing. The test is valuable for implementations which implement the sideways variant, and we shouldn't decrease their test coverage to make a number go up. :).

+1 to Ian. The more I thought about it I agree that we shouldn't change the test... it is a totally valid test as is, it just covers an area we're not doing this year.

ping @nt1m and @jgraham

Good to remove the test from the suite instead of modifying it?

[nt1m]

that seems fine too

[foolip]

I've prepared web-platform-tests/wpt-metadata#4156. @jgraham WDYT?

[jgraham]

@emilio Does removing this test seem reasonable?

[emilio]

Seems reasonable

[foolip]

Cool, we have enough support for this now, I'll land web-platform-tests/wpt-metadata#4156.
