ISBAT Transforming Masonry Block -> Gallery Block -> hovering another image block crashes the editor

### Describe the bug:
Transforming Masonry Block -> Gallery Block -> hovering another image block crashes the editor.

### To reproduce:

1. Create a new page and add a Masonry Gallery Block with some images.
2. Save the draft and reload the page.
3. Transform the block into a Gallery Block.
4. Try to transform the Gallery Block into a Tiled Gallery.

### Expected behavior:

The block should switch from a Gallery block to another one.

I noticed that hovering is enough to trigger the error - you don't actually need to click on it.

What happens instead is that the editor crashes with the following error:
