Description Curtis Windatt CLA 2015-01-20 16:21:44 EST 
1) Have a one line CSS file containing an @import statement
2) Ensure validation options are on to mark @import statements with warnings
3) Hover the mouse in the editor, well below the annotation
Result:
The annotation tooltip opens

The problem is that textView.getOffsetAtLocation will try to find the closest valid offset to the location.  If the annotation is on the last line of the file, hovering anywhere below that line will still return the last line.  Something similar might happen for hovering above the first line, but as the text view area starts at 0, there is no where to hover within the text view but above the text.
