WPopupMenu gets cut off at layout-boundaries/scrollbars
I have a WHBoxLayout which contains two WContainerWidgets side-by-side left and right.
The left container has
setOverflow(Overflow::Auto) assigned, to have scrollbars available.
Any WPopupMenu inside the left container gets cut-off at the scrollbar (see image attached).
When I temporarily remove Overflow::Auto the popup is shown correctly, but this is not the solution :-)
Affected version is Wt 4.5.0 and all web-browsers (IE, Edge, Firefox) using Windows 10.
