Reviewed by Ryosuke Niwa.

Added null check in updateHighlightPositions for position.
In special test cases where there are identical ranges,
positions used to be overridden, first set to a non-null position,
then set again to null, flipping back and forth.
Changed TestExpectations due to more tests passing.
