Contribution that tracks mouseup and mousedown events.
This is required to be able to track the TabBar, DockPanel, and SidePanel resizing and drag and drop events correctly
all over the application. By default, when the mouse is over an iframe we lose the mouse tracking ability, so whenever
we click (mousedown), we overlay a transparent div over the iframe in the Mini Browser, then we set the display of
the transparent div to none on mouseup events.
