Bug 573546: Clear old selection in hover on annotation ruler

Browse source 
The select can be called twice when the expansion first opens,
so clear out the old selection before processing the new one.

If this isn't done, the oldStyles gets set to the highlighted
version on the second call, which prevents deselect from
removing the highlight.
