Text has custom formatting but I can't see the details
In the attached example I added two tempo markings. Looking at them in the inspector, the "Remove Custom Formatting" button was active for both. So for the second marking, I clicked Remove, and its appearance changed visibly.
Now I was curious to know exactly what custom formatting I just removed, and I thought I should be able to double-click the markings to enter edit mode, and by moving the cursor around while watching the toolbar I would find out that one of them has some character in a different font, or different size, or italicized, etc. But as far as I can see every character in both markings is Edwin 12 pt bold, including the quarter note glyphs which look obviously different. Is there a kind of "custom formatting" that is hidden from the UI?
