Describe the bug

1. Start dragging the "Hover me" button
2. Try to put it above the "All text blocks could be edited easily..."

What is the expected behavior?

• The layer manager can be used to reorganize elements

What is the current behavior?

• The button can be only dropped at the beginning of the container
• Dragging within the layer manager has the same limitation

I've tracked down the breaking change in Firefox to version 109.0. It's the first one that has the problem. Version 108.0.2 works fine. Hope that helps.

I have also tested 133.0a1 nightly from 2024-10-24-21-16-15-mozilla-central and the problem is also there.

When can we expect this fix to be released?
