Wt

Affected Wt 4.12.2 (and former versions, checked down to 4.11.4).

WMenu looses all previous style classes on the first call of addStyleClass.
Workaround: re-add the missing style classes

addStyleClass("dropdown-menu");
addStyleClass("Wt-popup");

STR:

• run attached main.cpp
• open http://127.0.0.1:8080
• click "Add many context menu items"

--> Complaints about missing style classes in the trace (refer to ensureStyleClass).
