Problem

When a table is the only block on a page (or the first/last block), there is no way to place the cursor before or after it -- neither by mouse nor by arrow keys. Users cannot add a paragraph above/below the table.

Reported by Stefan on 2026-08-15 while working with v0.15.0 on a production instance.

Likely cause

ProseMirror needs the Gapcursor extension to offer a cursor position adjacent to block nodes that have no text position of their own. Either it is missing from our editor setup or it does not cover this case.

Scope

Verify/enable gap cursor for tables; check other leaf/block nodes in the same situation (code blocks, images, Mermaid, embeds) as first/last/only block.
Arrow-key navigation must reach the gap positions (relevant for the accessible table exit in the Tab-navigation issue).

Acceptance criteria

With a table as the only content, the user can place the cursor before and after it (mouse + keyboard) and create a paragraph there.
Same for other block nodes at document edges.
e2e coverage in the editor pack.
