Incompatible with diff module

I think that the relevant change is the addition of the route subscriber in https://git.drupalcode.org/project/wse/-/commit/69838e13489891a9995fe8f8...

We can do something like this in WSE, but we also need an issue in the Diff module to factor out getting the revision IDs from \Drupal\diff\Form\RevisionOverviewForm::buildForm() into a separate method, because overriding and copying all that code is a bit too much to do in this module.

Once we have that issue (and patch), we need to extend this patch and override \Drupal\diff\Form\RevisionOverviewForm.
