1703146 - WPT tests flexbox-writing-mode-013.html through -015.html fail, probably due to subtle alignment bug in the testcase

Status: RESOLVED WORKSFORME

(Core :: Layout: Flexbox, task)

Description

[Daniel Holbert [:dholbert]]

These three tests fail in Firefox Nightly:

https://wpt.fyi/results/css/css-flexbox/flexbox-writing-mode-013.html?label=experimental&label=master&aligned
https://wpt.fyi/results/css/css-flexbox/flexbox-writing-mode-014.html?label=experimental&label=master&aligned
https://wpt.fyi/results/css/css-flexbox/flexbox-writing-mode-015.html?label=experimental&label=master&aligned

(#13 passes in Chromium; #14 and #15 don't pass in any browser.)

At least in Firefox, they all seem to be off-by-1px sorts of issues, so seems likely to be a test bug. Looks like I'm the author for all of these tests, so I don't feel too bad about messing with them. :)

(Also, FWIW, these tests are excluded from the compat2021 test set right now.)

(Also:, tests -014 and -015 are too tall for the WPT test harness's viewport-size; some of the tested content runs off the bottom of the viewport and gets clipped. This might be because they were originally reftests, which IIRC had a more generous viewport-size than the WPT test-harness does.

All three tests pass in Firefox now (as well as Chromium). --> Resolving as WORKSFORME.

(Not sure what changed; the tests themselves don't seem to have changed since when I filed this bug. Maybe something about the wpt.fyi test harness / CI-system changed? Anyway, I'm glad they're passing. :) )
