Bug 212054 – [css-flexbox] WPT Test css/css-flexbox/flex-lines/multi-line-wrap-reverse-column-reverse.html fails

• Component: CSS
• Status: RESOLVED FIXED

[Carlos Alberto Lopez Perez]

The WPT test css/css-flexbox/flex-lines/multi-line-wrap-reverse-column-reverse.html fails on Mac and iOS

The failure its just some small pixel differences in the text rendering, likely related to font kerning differences.

See: https://wpt.fyi/analyzer?screenshot=sha1%3Acd49a443027a6deb9e65fdec779db7fd2a3ed532&screenshot=sha1%3A28b192ce9f5c2d626bf5243b8b3e3fa79652cfb0

This test passes on GTK/WPE.


Likely this test can be fixed by using Ahem font.


For a very similar issue on other of this tests see bug 211891

r=me, the change looks good just a minor comment about using red color.
Apart from that I'm not sure if I need to review the PR in WPT or it's enough with the review here, please let me know. Thanks for the fix.

Please avoid using "red" for things that are on the expected output (as red usually means wrong behavior). Just change it for another color.

That is not necessary. There is a bot that will approve the WPT PR after getting review here. Check: https://trac.webkit.org/wiki/WPTExportProcess

Sure, I will use orange instead.

Thanks!
