can't dismiss user dropdown in lessons; accessibility issues

In lessons, if you pull down the menu from then user icon in the upper right you can't close it.

I never found the cause, but a fix is in morpheus.scripts.min.js, in function toggleUserNav,

change

a.on("click",function(){$(b.target).trigger("click")

to

a.on("click",function(){$('.js-toggle-user-nav .Mrphs-userNav__drop-btn').trigger("click")

There's already dependency upon specific classes in that function, so I don't think this should be an issue.

-------------------

While you're looking at it: this isn't a reasonable way to dismiss in a screen reader. The standard approach is to bind the ESC key to close the menu. But I think I'd also put a close button in the upper right of the box, as everything else in Sakai does.

In general I recommend using jquery dialogs rather than rolling your own.
