    "/admin/config/content/entity_browser/test_entity_browsertest_entity_browser/widgets",
    but "/admin/config/content/entity_browser/test_entity_browser/widgets"
    expected.

Re-ran the job and it passed: https://git.drupalcode.org/project/entity_browser/-/jobs/465607

I didn't change any code in-between. I've been seeing this failure a lot.
