Unfortunately, no progress here, sorry. The main issue is that we don’t spend time doing screen reader testing with JAWS, we only test with NVDA and VoiceOver on the Mac. JAWS requires a licence for users and it’s Windows only, which makes it much harder for our team to use. We’re generally Linux/Mac users and prefer open-source or free software to proprietary. JAWS is the most popular, but their fees are quite high. Even online services that offer rentable accessibility testing (like BrowserStack and AssistivLabs) don’t offer JAWS at the lower pricing brackets.
That said, I’m going to mark this as pr-welcome which means that members of the community are welcome to submit a fix for this issue.
