Hey,
I found a bug. Please, see attachment.
BTW: there are regression found after updating to the latest git
(I believe after fixing WMenuItem's memory issue). After running
my test case (or any code which calls new WMenuItem(...)
you'll see Segmentation fault error!

// Bug report.
// Description: incorrect WMenu internal path handling for submenu items.
// How to reproduce:
// 1) Open URL: host (or host/search)
// (works as expected)
// 2) Open URL: host/settings
// (OOPS, submenu does not handle internal path at all since
// unnecessary check -- if (!parentItem_) in
// WMenu::handleInternalPathChange(const std::string&))
