Safari: Block toolbar doesn't always appear for the selected block

[kjellr]

Description

In Safari, selecting a block does not always result in the block's contextual toolbar being displayed. The block does receive the blue "selected" outline, but the toolbar does not appear. I notice this issue most frequently when working with nested blocks, though I'm not sure if it's restricted to that scenario.

I've only experienced this issue in Safari.

Should be fixed after #30995. Please reopen if that's not the case :)
