Test case

See the attached test case. This happens because of the (characterIndex > 0) test in ComplexTextController::adjustGlyphsAndAdvances(). In the test case, the run boundary before the space is the result of a change from the small caps variant to the normal variant, but a face change (because of fallback) can cause the same behavior.
