Category headers in some screens still can't be selected

Despite the fix for MC-310717 in 26.3 Snapshot 9, category headers in the Edit Game Rules and Debug Options screens still can’t be selected, neither with the mouse nor the keyboard.

Steps to reproduce:

1. Open the Edit Game Rules or Debug Options screen.

2. Try to select one of the category headers.

3. Open another menu that has category headers, e.g. Video Settings.

4. Try to select one of the category headers.

5. Observe the difference in behavior.

Expected result:

Category headers would be selectable in any screen that has them.

Actual result:

Category headers can’t be selected in the Edit Game Rules and Debug Options screens.
