Description

Repro:

  1. Install Luna Paint
  2. Make a change to an image
  3. Save it
  4. Click the change in the SCM view, the diff should load
  5. Click the tab, the diff custom editors will both reload

This doesn't seem to happen with text editors.

No gif as gifcap is acting up on edge and safari atm.

Contributor guide

Research direction
Investigate the code path for custom editor reload when clicking a diff tab. Look at the editor group and tab handling logic in VS Code's source, specifically around how custom editors are cached and reused compared to text editors.
