when running tests in CI on a newer version of linux (18.04 -> 24.04) we run into some new perma failures.

in this debug log, you can see this failure:

this bug will be for tracking investigations, I will be skipping these tests in a manifest in a larger patch to green stuff up.

The test works fine on my local Ubuntu 24.04.

ok, so something in our docker image/config is the problem.

Looks like some UA specific styles for button breaks the test.
