Research direction
Start by reproducing the issue: open a file, modify it externally, and trigger the editor's reload. Trace the reload and undo/redo handling in the relevant editor code. Done means the externally reloaded version is undoable, redo is disabled, and undo restores the prior in-editor version without losing subsequent history.
