Notice that when bootstrap is at play, the added padding to the input does not allow mouse events to come through in Firefox.
After removing padding on the input does the mouse event trigger correctly
Which mouse events are being blocked?

@R2D2VaderBeef Yeah, it's an unfortunate bug. Our QA found this and I don't know how to fix it. Pseudo selectors won't do the trick either
