Toolbar dropdowns don't hide on front end on tap away

[miqrogroove]

In the wp-admin pages I can open the Howdy or New menus and tap away to close them.

In the front end admin bar, the menu stays open until navigating to a new page.

Found on 3.5-beta3-22637 using iPad3 iOS 6.0.1.

Does your front end have jQuery loaded? I'm not sure if we included a fallback for non-jQuery (which we should probably address)

It does not. I double checked this happens in Twenty Twelve. IMO, the front-end admin bar shouldn't use jQuery at all unless it is included.

I recall it being like this on both the front and in the admin previously (3.4.2 and before), at least on iOS 5.

I'm conceptually fine with doing it in jQuery with a slightly-less-functional fallback if jQuery isn't loaded. But we need to let people close the menus as a minimum.

We don't currently enqueue jQuery on the front end, nor do I think that we should just because of the toolbar.

Yeah I'm in favor of the fallback.

Not a "regression" for 3.5.
