    Description

      With Qt 6.x windows having the Qt::FramelessWindowHint flag set are now resizable by dragging the the window edges. This was not the case with Qt 5.15 and also contradicts the documentation which says "Produces a borderless window. The user cannot move or resize a borderless window via the window system".

      Please compare the behaviour of the "WindowFlags" example when build against 5.15 and 6.3.

      Maybe this is caused by 4c78ef80ca7. This unconditionally adds NSWindowStyleMaskResizable to the cocoa window flags.
