Tool-tip obscures pointer at screen edges

When the clip editor is located at the bottom of the screen, when we move the pointer to some of the buttons at the bottom, such as Play, Rewind etc, the pointer can sometimes be obscured by the pointer, not allowing for the button to be pressed.  The pointer must be jiggled around until the tool-tip closes.

The picture below shows a clip editor example, the pointer is hovering over the play button, but this button can't be pressed because it's obscured by the tool-tip. (I've painted a pointer as screenshot does not capture the windows pointer)

This is a relatively frequent issue when unity is full screen and the clip editor is at the bottom of Unity.

It's not a game breaker, but it's a bit irritating at times.
