This reminds me of  issue 599433  and  issue 643578 , but may not be related. Taking a look.

Trying this on 63.0.3239.59, I don't get the same version of twitter.com. I've seen this "What's happening?" version of twitter several times in reports from etouch.net, but what do I need to do to get this same site?

Trying the repro steps on the version of Twitter that I do get, the scroll position changes slightly, but I'm not scrolled to the top of the page as reported. That's very similar to  issue 708296  where it turned out to be something that the script of the page was doing.

I'm trying to get access to a proxy service so that I can try this with an IP in India, but if there's anything I can do in the meantime, please let me know!
