[CSS Shapes] Image shape-outside with vertical gaps is handled incorrectly

[CSS Shapes] Image shape-outside with vertical gaps is handled incorrectly

RasterShapeIntervals::getExcludedIntervals() was returning an empty list when the line overlapped any vertical gap in the image. This short-circuit had been mistakenly copied from getIncludedIntervals(), where it makes sense.
