ubuntu dock bounces when on bottom and auto-hide is active

[Russell Weber]

While dock is locked to the bottom of the screen and hidden while not in use, once un-hidden/activated it will bounce back and forth between hidden and un-hidden. This is much more apparent or frequent when there is a window that is either maximized or has a boarder near the bottom of the screen next to where the dock will be activated at (Usually the bottom 10 or 20 pixels of the screen).
This is potentially a GNOME issues or an "Ubuntu Dock", issue. However, I don't have the time at the moment to diagnose this further.

Attached is a video which shows the bug in action.
