Description Fernando Marcelino Muniz 2026-03-18 01:59:24 UTC 
STEPS TO REPRODUCE
1. Click on the vertical triple dots, then click on "Configure columns" button.
2. Hold a click on the scrollbar and move it up and down.

OBSERVED RESULT
The scrollbar is only moving when the click is released, like Windows 95 or older.

EXPECTED RESULT
The scrollbar should move in real time like all the other ones when a click is being held on it.

table: Port ColumnConfigurationDialog from Dialog to Window

As it turns out, Dialog with `popupType: Window` has too many bugs for
things to work reliably. So instead, use QtQuick Window as base and
reimplement some bits of Dialog to make that work properly, since I do
rather like that it's a separate window.
