I've realized that the Bootstrap 2.3.2 tooltip doesn't always work properly. I'm having this problem in :
It seems to work well in IE 9.
If you move the mouse over the tooltip element quite fast (up and down, for example, or right and left), there's a point in which the tooltip won't show when you have the mouse over the element which is suppose to show it.
You can easily reproduce it in this fiddle.
$('[data-rel]').tooltip()
Did anyone find a solution for this?
Update
Fiddle to reproduce it.
