Is Mobile Safari's in-app multitasking (audio stream in one tab, browsing in another) gone for good?

Question

I cannot remember the last iOS version this feature actually worked, but in the past, I used to be able to open a tab in Mobile Safari, begin streaming audio from a website, pinch in to bring up standard UI again, and then open up another tab within Safari itself and continue to browse the web. All the while the streaming audio is still playing in the background.
Now (and actually for the last few iOS versions, it's been a while), you cannot browse Safari while listening to a Safari audio stream at the same time. To me this makes no sense at all, because it's just a simple backgrounding concept. I can go off and use any other app on my phone, but not Safari itself.
There ARE a few ways to kind of trick Safari into allowing you to browse and listen, but it's a poor workaround. You can go to the website, tap-and-hold on the stream URL, then select Open in Background. Doing so will begin the stream and keep you in the current webpage and then allow you to open more tabs.
HOWEVER, if you ever select that audio stream tab, you can't control it consistently, and most of the time you'll get stuck in that tab and your solution is broken.
For YEARS I've been waiting for Apple to fix this silly limitation with each new iOS release, but every time I find that it's never fixed. I'm just surprised that I don't hear more people complaining about it, because it's been a huge source of frustration for me for so long.
Does anyone else experience this frustration or know if this is intentional (which would be enormously depressing if Apple purposely designed these functions) or if there are any better solutions to it than what I've come up with?

Thanks for the heads up.
Odd that I can't just email their support department.
I'll post back with my results.
