Clicking on CSS property in Quick Editor doesn't work for global classes

I’m guessing this is more of an unfinished feature than a bug, but just in case not…

When using the Quick Editor from the Navigator, clicking on the CSS property takes you to related screen in the Block Inspector (super useful).

When using the Quick Editor on a global class, clicking the CSS property does nothing.

I experienced the same. Quite a few properties do not work.
Talking about regular block classes.
