Qt6.9: Resizing QML dialogs is glitchy

[krasko78]

Issue type

UI bug (incorrect info or interface appearance)

Description with steps to reproduce

1. Make sure you are using Qt6.9.
2. Open the Preferences dialog or the Parts dialog and resize them.

Actual: Very weird visual glitches.

Video:

resizing_glitches.mp4

Also note in the video that when the resizing stops and the glitches remain, moving the mouse over the OK and Cancel button does not hover them. Clicking them does not click them. This is because the glitches on the right and bottom side of the dialog cause the buttons (the entire dialog is screwed up actually) to move visually away from their normal positions. Interestingly hovering and clicking where they should be makes them hovered and clicked.

All resizable QML dialogs seem affected.

There's an argument to be made here to not allow resizing these two dialogs at all. They already have a minimum size, and making them bigger doesn't responsively re-layout the UI in any purposeful way.
