Hey Jeff. Thanks for the reminder about the read-only link. Didn’t realize that allowed people to work in the designer. I’ll drop it below. In the meantime, let me be a little more clear one what I did:
Added a Heading, gave it a class, gave it a combo class, then tried to use the Inherit dropdown to return and edit “All H2 Headings.” If I selected the Mobile option up top, the clicked the menu to select “All H2 Headings” the only option available was the Desktop breakpoint of that tag. Similarly, if I selected “All H2 Headings” THEN switched to the mobile breakpoint, it would kick me out of the tag, and put me back to the Class / Combo Class. Now that I’ve added the style guide page, and adjusted the h2 tag there, the option to select “All H2 Headings” with a mobile breakpoint is available, but it shows as a separate tag (kind of…see image) in that step. Issue persists with the “Tablet” breakpoint, because I didn’t set anything there on the style guide page.
