Description

While testing the new WordPress 6.7 beta with our plugin, I noticed a strange shift in the block toolbar that did not occur in version 6.6.x.

All the elements inside the block that are generated in the “edit area positions” are absolutely positioned, so there is no width/height change to the block.

I saw in the Gutenberg repo that the block-popover has been updated with some new calculation methods, so perhaps there is a new restriction for elements inside a block when the toolbar is visible. (possibly related to dec82e2)

I understand this isn’t a bug related to a core block.

Step-by-step reproduction instructions

1. Install the free Advanced Columns plugin from the WordPress.org repository
2. Add the block to the page
3. Switch the column mode to “Grid.”
4. With the block selected, click on “Edit Area Positions” in the block toolbar
