Update off-canvas overrides after core refactoring

Would this need to go into a new branch as it would be incompatible with D9?

Patch in #3 worked for me. Thanks !

Looks like this might have been fixed in 📌 Automated Drupal 11 compatibility fixes for stable Fixed , can you please confirm?

Oh yes, it's been fixed and released.

Right, ideally this would be marked fixed and credit assigned to @fenstrat for the initial work 12 months before the D11 issue was created.

As per #8

Credit carry-forwarded in 📌 Automated Drupal 11 compatibility fixes for stable Fixed , hence closing this.

Automatically closed - issue fixed for 2 weeks with no activity.
