Drooping registered trademarks in cross references

[Reid Gray]

Hi Framers,
 
I have a cross referenced heading.  The heading includes a variable that includes a registered trademark.
 
The problem is that the trademark in the crossreference droops after I perform a book update.  I suspect Frame converts the character from subscript to normal after I update the book.  The variable definition  looks like this.
 
<Default ¶ Font>ACME<Superscript>®<Default ¶ Font>

Crossreferences in general seem to be quirky with Frame 8.  Yes?

Frame 8 with all the updates

Thanks,
 
Reid
