On Find and Replace, using `<Ctrl>-Z` doesn't re-search

[kuraga]

Description

On Find and Replace, using <Ctrl>-Z doesn't re-search.

Reproduce

1. Create a Jupyter notebook.
2. Type in the first cell: 123.
3. Open the Find and Replace dialog.
4. Type: 123 at the Find input.
5. The search indicator: - / 1.

On manual editing, the search indicator is updated:

6. Erase 3.
7. Type 3 at the same place.
8. 123 is highlighted; the search indicator shows - / 1.

But on undoing, it isn't:

9. Erase 3.
10. Press <Ctrl>-Z.
11. Expected: 123 is highlighted; the search indicator shows - / 1.
12. Actual: 123 is highlighted; the search indicator shows - / -.

Unfocusing the cell helps:

13. Unfocus the cell in some way.
14. Actual: 123 is highlighted; the search indicator shows - / 1.

Expected behavior

On Find and Replace, using <Ctrl>-Z re-searchs.
