WPopupMenu gets cut off at layout-boundaries/scrollbars

Description

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.

I've created a code sample that demonstrates the problem. This referes to Wt 4.5.0 and Wt 4.5.1.

Thanks!

Hi Stefan,

this indeed remains a bug, thank you for bringing it to my attention again. It's a very old ticket, but an issue nonetheless. It's a little similar to #13798, but differs in that here it should look at its "parent" to not be outside its boundaries, as to not disappear with overflow being hidden.

I've now scheduled it.
