Flickers when ng-repeat, bootstrap modal, fixed position is used in Firefox

FIRST EVERYTHING, THIS ISSUE DOES NOT PASS IN CHROME OR IE. ONLY IN FIREFOX.

I have a table filled with ng-repeat.

From the table, I have a ui-bootstrap popup and a fixed position div.

When I close / close the popup by pressing the "Esc" button, or pressing the Esc button, if I click again before the popup disappears completely, the fixed positioned div flickers.

Here is a plunker that mimics the problem.

To reproduce my problem, use firefox, open any of the three pop-ups and press Esc or click to close the pop-up. While the popup disappears, click again elsewhere and notice the fixed div at the top that will flicker.

AGAIN THIS ISSUE DOES NOT HAVE A CHROME OR IE. ONLY IN FIREFOX.

Thanks in advance.
