Popover Focus Trigger not working in Firefox and Safari
Created by: piperone
Using Vanilla Bootstrap 3.0.3, the focus trigger-option for popovers does not appear to work in Firefox 25.0.1 and Safari 7.0 9537.71 (on OS X Mavericks). It works as expected on Chrome, though.
No errors output to console, so I don't know what's wrong.
Hiding popovers on 'unfocus' should be a (working) built-in feature in Bootstrap given its relative widespread usage, so I'm sure a fix to this would be much appreciated by many developers.
