Actually, the message in the failure is

PDOException: SQLSTATE[HY000] [1524] Plugin 'mysql_native_password' is not loaded in Drupal\Component\DependencyInjection\PhpArrayContainer->createService() (line 77 of core/lib/Drupal/Component/DependencyInjection/PhpArrayContainer.php).

I forgot the test case after the failed one still spits out HTML output.

This is so inconsistent.

The latest commit passed 100/100 times on a Repeat run but failed in the normal test run.
Then I reran the Repeat run and it failed every single time.
