Description:
fast/css/identical-logical-height-decl.html

The first failure that I saw on the dashboard for Big Sur was 2/16/2022 at r289891, but this does not appear relevant to causing this issue.  The first failure that I saw on the dashboard for Monterey was 3/19/2022 at r291536, but this does not appear relevant to causing this issue.  This test seems to have been flaky since the start and affects wk2 x86_64 architecture. 

So far I have been unable to reproduce the issue including using a test list.

Another one with black snapshot.

t looks like the ‘failure’ in this case is the reference image is entirely black. The failing run also fails a lot of other tests in the same way, with one of the two images being black (not always the reference image).

I have unmarked this test as a flaky image failure while this issue is investigated, so we do not lose test coverage.
