Bug 116829 Label height doesn't change with label font modification.
Description: Label font size doesn't change right away it is modified. Steps to reproduce: 1. Add a label and edit its font size as "18 points". 2. Label height is not changed right after setting in UI. 3. Change label content, its height can be justified with the font size.
