[random test failure] Random failures building media library form after uploading image (WidgetUploadTest)

1500x is too much in one go, whenever a patch like this hits the 50+ minutes, "wonky" things happen.
Let's see if we can keep it below that in a 1000x patch

Fails on the test runs with and without 🐛 [random test failure] Drupal\Tests\layout_builder\FunctionalJavascript\LayoutBuilderUiTest::testReloadWithNoSections() Fixed , so that's not the solution for this one.

I believe this random test failure doesn't appear anymore.
To prove this, we need about 5000-8000 runs failure-free runs of the suspicious test.

Let's try that here. I use 500 runs in one patch, since any time the repeated runs of this test get's over 45 minutes, things get "wonky" and unreliable. The 500x run should finish within 30-35 minutes.

The fails are

upal\Core\Installer\Exception\InstallerException: Resolve all issues below to continue the installation. For help configuring your database server, see the installation handbook, or contact your hosting provider.Failed to connect to database. The database engine reports the following message: SQLSTATE[HY000]: General error: 5 database is locked.Does the database file exist?Does web server have permission to write to the database file?Does the web server have permission to write to the directory the database file should be created in?

we can just ignore that IMO, looks solid otherwise.

Agreed, this "somehow" happens (randomly) when running single Functional(Javascript)Tests a lot of times.
Seen this happen on a lot of my fix-the-bloody-random-failure-and-run-it-500+-times patches and they are (at the very least) not related to the test that is the SUT.

As far as I'm concerned: This random test failure is gone (for now).

Unsure what should happen with this issue.
I've seen older similiar issues being closed as cannot reproduce. If needed they can be found in the search and reopened (See for example 🐛 [random test failure] Random failure in CommentStatisticsTest Fixed )

Yep, let's close as cannot reproduce, and this can be reopened if it starts appearing again.
