Description

In multiplayer, if user A is editing a link in a text shape's rich text toolbar and user B deletes that text shape, the link editor stays open with no way to dismiss it.

Steps to reproduce

1. Open the same room in two browser tabs
2. In tab A, create a text shape with some text
3. In tab A, select the text and open the link editor in the rich text toolbar
4. In tab B, delete the text shape
5. In tab A, the link editor remains visible and stuck

Expected behavior

The link editor should close when the underlying shape is deleted.
