"Block description" label not clear & not consistent in edit form of inline blocks

This makes sense to me.

Rather than using a hook, is it possible to set the new admin label in Drupal\layout_builder\Form\AddBlockForm::buildForm instead?

This will also need test coverage of the new label coming through. It seems like overkill to add an entire new test case for this, so maybe an assert for the new admin label could be added to LayoutBuilderTest::testFieldBlockLabel?

Thank you for your feedback and suggestions. I implemented the changes.
I set the new admin label in Drupal\layout_builder\Form\ConfigureBlockFormBase::doBuildForm instead of Drupal\layout_builder\Form\AddBlockForm::buildForm because that's where the admin label is being set to "Block description" by $form['settings'] = $this->getPluginForm($this->block)->buildConfigurationForm($form['settings'], $subform_state);

Works as described!

This is failing tests at the moment, they need to be passing before this can be RTBC

It looks like these tests fail since the last commit in issue https://www.drupal.org/project/drupal/issues/3272629 🐛 Media Library widget display doesn't return to first page on applying filters Needs work , pipeline: https://git.drupalcode.org/project/drupal/-/pipelines/143737

Thanks for working on this. MRs should always be created against 11.x first, and will be backported to the appropriate versions once the issue is committed. (Sometimes, the cleanest thing to do is to close the old MR and open a fresh one against 11.x.) Thanks!
