menu widget broken (?) after update to 1.11.0
I'm looking for some help for an issue I am facing: I have just updated jQuery UI in our web app, and the menu widget started behaving differently than before:
1. the menu no longer has rounded border
2. when a menu has a submenu opened on hover, the submenu text is white/hidden
I am attaching two images that display the same menu before and after the update.
The menu itself is a nested set of <ul/> which contain <li/> which contain <a/> tags.
I'd like to stress that I made no change whatsoever, I only update jQuery UI from 1.10.4 to 1.11.0, both js and css files.
