This extension loads the [ProseMirror Gapcursor plugin](https://github.com/ProseMirror/prosemirror-gapcursor) by Marijn Haverbeke, which adds a gap for the cursor in places that don’t allow regular selection. For example, after a table at the end of a document.
Note that Tiptap is headless, but the gapcursor needs CSS for its appearance. The [default CSS](https://github.com/ueberdosis/tiptap/tree/main/packages/core/src/style.ts) is loaded through the Editor class.
