Bug 216770 – [GLIB] imported/w3c/web-platform-tests/css/css-flexbox/flexbox_stf-table-singleline.html is an image only failure since r267183

• Component: CSS
• Status: RESOLVED FIXED

[Diego Pino]

These two tests started failing in r267183:

  imported/w3c/web-platform-tests/css/css-flexbox/flexbox_stf-table-singleline.html
  imported/w3c/web-platform-tests/css/css-flexbox/flexbox_stf-table-singleline-2.html

The tests were marked as ImageOnlyFailure, but were removed from test expectations in r267183. The post-commit bots report these tests as ImageOnlyFailure since then.

Do all ports report that issue?

I say this because I locally have a 1px diff in those tests but it's caused by font rendering.

Since the tests were removed from test expectations in r267183, these two tests are passsing in iOS and Mac, for example, but they're failing in GTK and WPE.

Yeah that's what I have observed too. The thing is that the failure is caused by a 1px difference rendering fonts. I'll submit a PR to wpt which sets the Ahem font because the actual text is irrelevant for the test.
