I confused the place of error. It seems this is what was said here #2848177-14: More \Drupal\Tests\outside_in\FunctionalJavascript\OutsideInBlockFormTest random fails.

Ok I was working with @drpal the yesterday and we were seeing similar random fail on this local.

We fixed it by removing all animations for testing. Could this a solution? We don't actually test anything in relation to animation transitions in our tests. Why do we need them?

This patch adds removing all transitions to core/modules/outside_in/tests/modules/outside_in_test_css/css/css_fix.theme.css which will already use because our testing doesn't work pointer events CSS.

I am also uploading at patch with only changes being the running the test 30 times. To test if we are likely to get a random fail.

Constantly worrying about turning off the animation for a stable passing of tests seems a little tedious, although it probably makes sense.
What if we add a patch from #2848177-14: More \Drupal\Tests\outside_in\FunctionalJavascript\OutsideInBlockFormTest random fails?

I overlooked that all transitions were canceled globally. Good idea! Enhanced testing was launched.

Well, #5 looks nice. I created another issue to solve the problem of stability tests due to CSS rules. So, we can add it like @todo for current solution, or not. In any case, +1 to RTBC with #5. This will help to quickly solve random fails of tests such types. Thanks!

Since @vaplas +1 rtbc for #5 here is the patch with only the needed test change

We also already have follow to see if there is better way to test animations #2901792: What to do with testing css animations?

These two comments should have whitespace before and after the words. And maybe punctuation?
And it leads me to wonder what exactly the first section is, can it get a comment too?

This looks good, and probably needed until we can migrate away from Phantom.
