I ran into the same problem just randomly clicking in the editor with some text in it. It crashes here.

Apparently, the problem is in this expression e.getSelection()?.blocks || [e.getTextCursorPosition().block] in useSelectedBlocks. I guess, of e.getSelection()?.blocks returns an empty array, we need to take [e.getTextCursorPosition().block], but in current implementation we won't since [] == true.

Or maybe we just need to check if block is undefined

Fixed in this commit.

Was caused by setSelectionToNextContentEditableBlock not stopping after reaching the last block in the document.
