@robintown also the mx_Heading_h4 heading is a lot bigger now. It doesn't looking really good in the right header playwright/snapshots/polls/polls.spec.ts/ThreadView-with-a-poll-on-group-layout-linux.png for example.

I wonder what is the best approach:

• Change the heading to body-lg-semibold
• Or only change in right header

I think the current pattern in which h1, h2, h3, h4 map directly to our heading/xl, heading/lg, heading/md, heading/sm design tokens is pretty nice. If we keep wanting to use body/* tokens as headers, that's an indication that we should change something about our design system IMO. Germain noticed this too: element-hq/compound#154

Hmmm you're right. I have the feeling that we are missing smaller tokens for heading. Maybe that's why designers are using body token for small headers.

Let's keep it in this state in this PR and we will have the conversation and update it if theses changes are not welcomed.
