Tooltip is occasionally hidden when the corresponding object is hovered

Created by: bobrovnikov

I stumbled upon this when working with popovers (which are dependent on tooltip plugin). If you catch a moment when tooltip fade out animation is in progress and hover over the object in this time span, you will find yourself in a situation when the object is hovered but tooltip does not reappear.

Here's a screenshot from bootstrap official website. It took me about 5 seconds of violent moves between the button and tooltip on the left to reproduce the issue.
