Why do we assign the is-selected class when useBlockProps is responsible for this?
And could we also revert the change here: 748c632#diff-4501da117949f251043d70ffccf02c54af2a99fb80ccd33eb2d40175acdfc833L153?

I don't know to be honest. Might just have been a visual thing.
It was originally added in this PR - #17832 - which has a lot of comments, it might have been discussed in there at some point.
I'll remove that line.

Ah, sorry, should have linked this one too: 748c632#diff-4501da117949f251043d70ffccf02c54af2a99fb80ccd33eb2d40175acdfc833R165

Have removed both of the modified lines, and it still seems to work, so hopefully there's no drama from that change (cd3aa0c).

If there's a problem we look for a pure CSS solution. :)

If we do want to make style changes based on a block being dragged, we should use a dragging class in combination with e.g. |

Description
Fixes #30177.
The thing that triggers the error is the call to the
isDraggingBlocksselector. I'm not sure why yet. I'll do some more digging to try to fix the root cause.But this can serve as an intermediate fix.
To resolve the issue I removed a bunch of code related to that selector, and I don't really know what some of it does. It looks like one use of
isDraggingBlockswas to hide the appenders in the nav block when dragging. I don't think it's a big issue if these are visible again.The other cases modify the
is-selectedandis-editingclassnames. It's unclear to me what that might do, but it might be that there was a need for this originally, but now there isn't (the feature still seems to work ok without this).How has this been tested?
Try dragging a navigation link (including into a nested submenu)
Expected result: The block should be drag and droppable.
