Window close button not clickable for some windows

### Description

It seems to occur only for some of the windows called by right-clicking: for right-clicking on a table in the Database Navigator, the issue occurs for `Export Data`, `Import Data`, and all windows called from the `Tools` submenu.

The issue is: the window close button (the "Truncate table" window in the screenshot) ~~cannot be clicked~~ does not react to simple clicks. It seems to be covered by something.

If I double-click it, the window will maximize. When its window is in the maximized state, the close button behaves the same - nothing at simple click, unmaximize at double-click.

Seems related to #23417, although I am on Linux/KDE, not on Windows.
