Hi
I have manually tested MR 602 on Drupal 10.3
the MR is applied successfully...

After Applying MR Block content add form have sidebar.

Adding Screenshots

keeping in need review for code verification

Hi there, I have also tested MR602 on Drupal 10.4.6 and it's working for me. +1 for RTBC.

hello, I have tried to replicate this issue on Drupal 11, Gin theme version 4.0.x. I am not able to replicate it. Added screenshots below for reference.
If it does not replicate anymore, we can close it.

This issue is reproducible, and the MR effectively resolves it. Previously the Revision block was not rendering in the sidebar, as shown in the attached "before" image. After applying the fix, the block renders correctly, as seen in the "after" image.

Based on this, I am moving the issue to RTBC.
