Undo affects the main file even if you press Ctrl+Z while in Find (and Replace)

[KeronCyst]

Xed 3.8.9 on Linux Mint Cinnamon 22.3, 'Zena':

1. Open a document and type stuff in it
2. Open Find or Find and Replace and type and delete stuff in any of these query fields
3. Undo

Expected result: All action should stay local to the Find or Find and Replace pane

Current result: The action jumps back to the main body, undoing whatever you had last typed there instead of in the Find pane
