Bug 1936985 and bug 1937573 are already in review. The only one that seems like it might be tough to figure out is bug 1936985 given we currently have no way to determine from the stylesheets when a tab has reached min-width, but perhaps we can find an short-term workaround for this and file a follow-up to address that? I'm working on bug 1937534 now. I think we just need to add back the old svg that had the circle built-in. I've just left a [comment](https://bugzilla.mozilla.org/show_bug.cgi?id=1937268#c8) on bug 1937268 to say that this will somewhat be improved when bug 1936985 lands as we're decreasing inline-margin around the audio button there, but we're not going to have as much as the tab title visible when a user has many tabs open and the audio button is present, that's just the nature of this new design requested by UX. So as far as I can tell, that's just 3 bugs that are open and 2/3 are in review.
