Description

When I set the locking option on a group (grid) block, with "Disable movement" UNchecked, to allow only moving child blocks, it doesn't seem to work as expected:
Moving blocks around with the toolbar arrows works, but drag and drop within the toolbar or the sidebar does not allow moving blocks.

Step-by-step reproduction instructions

1. Open a page in the editor
2. Add a group block (I tested with the grid variant)
3. Add 3 images as child blocks
4. Drag and drop child blocks in sidebar, and notice this works as expected
5. Set the group lock option to "prevent removal" and apply to all blocks inside
6. Try drag and drop again, it does not work, but the toolbar arrows do work
