Bug Description

When dropping text, prosemirror attempts to calculate the insert position via posAtCoords. In this case, it uses the element's bounding box. So if the cursor gets there, rather than adjusting the position, it assumes that the insertion occurs at the depth level of the table rows and looks for suitable neighbors for the new element and finds tableRow.

A table that is created in this way is invisible and broken. It cannot be deleted via Backspace (throws error), properly selected, etc. To reproduce it, you can just go to the example from the tiptap website

There are many places where it is possible to handle this case both in prosemirror modules and outside the prosemirror logic, although it should probably be considered as a bug of prosemirror itself.
