comment: should set the styles to default to those of h3 now

If we are to still support this behaviour then this should be defaulted to the h3 styling (previously it was h2 styling). It might be worth speaking to the team to ensure that we want to keep this behaviour as it's not completely clear from the ticket.

We also need to ensure the DS is updated as this no longer matches what is supposed to be the source of truth. So, it could be worth speaking to @harpalsingh to make sure that gets updated if this is to be correct. I'd be reluctant to approve this until it does match the source of truth.
