Given a ScrollContainer containing a Label and the default created vertical Scrollbar. How can I prevent that the shadow of the highlighted grabber is clipped? The shadow is set via the Theme Editor and the theme preview is shown correctly. During runtime the shadow is clipped always on the right side and on the top/bottom, if the grabber is at the top/bottom position of the ScrollBar.
For the grabber highlight property I selected a StyleBoxFlat element with a shadow size of 5.
Thanks for any suggestions!
