The only config property needed for this test is 'status' => TRUE, while the additional config is not doing any harm, I prefer not adding anything that isn't directly relevant to the test.

Re #5

Those settings are copied 1:1 from the annotation of \Drupal\media\Plugin\Filter\MediaEmbed — they’re exactly the defaults.

That pretty much lines up with my suspicions regarding why it was there because they certainly looked like default values. It may have zero impact long term, but I like that the test demonstrates that 'status' => TRUE is the only property relevant to that part of the process. Thanks for indulging the preference 😎

Committed c715824 and pushed to 10.0.x. Also cherry-picked to 9.4.x and 9.3.x because CKEditor 5 is experimental. Thanks!
