Problem/Motivation

The 9.4.x test fails a very simple patch which removes one line of CSS in #3212792: In ui-dialog box at Views button hover effect is odd ... So it looks like the general PHPUnit test for 9.4.x needs to be adjusted?

Adding test error message.

Why is this titled "Your XML configuration validates against a deprecated schema"? That is a warning. It is not the reason the test failed.

The test failure is "stale element reference: element is not attached to the page document". That seems like something that could occur based on CSS changes.

I do not understand this issue. Is this about the test failure or the XML schema deprecation warning?

I gave it that name because I thought that was the problem. Feel free to correct the title.

@longwave explained in the #3212792: In ui-dialog box at Views button hover effect is odd issue:

Triggered a retest on 9.4.x, sometimes we see random failures in the JavaScript tests that go away when the test is rerun.
The PHPUnit warning is unrelated, we can't upgrade until we drop support for PHPUnit 8.

In the issue, you will find a patch which removes a single line:
font-weight: normal/*{fwDefault}*/;
Do you think that could trigger the error? The patch passed with 9.3.x, so that's why I assumed the issue was with the test set-up.

If you mean "Your XML configuration validates against a deprecated schema", that's just PHPUnit complaining that phpunit.xml needs updating.

Thanks. The re-test triggered by @longwave passed, so it looks like a random JavaScript test failure.

In a similar issue (#3099427: [random test failure] FieldLayoutTest::testEntityView()) @catch explains a possible solution:

Unfortunately #3211164: Random errors in Javascript Testing will not fix this. What we need to work out is why the $second_region_row has been removed or replaced on the page. What possible triggers are there for that and if maybe we could use a different destination that cannot possibly be removed.
