Displayed font is incorrect until a change is made to the object

When opening a saved diagram, the font of some objects are displayed incorrectly until a change is made to it

I believe #129 mitigates this somewhat when a grouping existing in the file, since the version property of all objects get bumped upon opening the file, thus nudging the fonts to display correctly.

Same thing happening here. Any solutions?
