Scoped label rendering in emails is broken

Before the label style change:

After:

I think the unreadable text is an old bug but the new bug here is that :: is not rendered anymore and there's no space between them. The color only applies on the first half too because that's our new style, but not sure how we want to render this now.

We don't really render labels properly in emails even before this change, but now it looks more broken 😄
