Wt

Affected: WT 4.12.2 and former versions (checked down to 4.11.4)

STR:

• run attached main.cpp
• open http://127.0.0.1:8080
• click button "Popup nested"

--> Modal dialog "Nested Popup" pops up behind "Popup" and is invisible if "Popup" is wider.
The main window is grayed out but not the non-modal "Popup", which still accepts input.

(The first WDialog does not need to be non-modal, in order to further WDialog pop up behind it.
Though this is not reproducible with this demo app.)
