Bug Description

Escape does not close some modals after focus leaves the dialog, for example after clicking the backdrop or after an app token creation error re-renders the modal.

Reproduction Steps

1. Open the New folder modal.
2. Click the modal backdrop.
3. Press Escape.
4. Repeat with the app token modal after token creation fails with POST 500.

Expected Outcome

Escape closes the active modal.

Actual Outcome

Focus moves to the page body and Escape no longer closes the modal; only the close button works.
