@sm , great, thanks for the confirmation. I'm on the infrastructure side of the fence so I'll need to liaise with one of our devs to look at this in more detail, but it's good to get confirmation that it is at least consistent for you across providers.
For what it's worth, I have an Aussie Broadband service in Tasmania that I use, and a Telstra service in Brisbane, and both work just fine. I think it's pretty clear this is a JS problem like you say 😃 . I'll get back to you on this when I can.
