Tooltips cannot be dismissed on iOS

Created by: upngo

Tooltips can be shown on mobile by clicking, but you cant get rid of them.

They swallow up click events too so you can't add click handlers to the body to hide them.

Same as the problem noted in #3417 (closed) #6232 (closed) - both full of exasperated users..

If this isn't going to be fixed, at least a note could be put in the docs saying don't use tooltips if you want it to work on mobile without custom code disabling them for mobile devices...
