[orca-list] Performance issues on https://rocket.chat

[Nolan Darilek <nolan thewordnerd info>]

Tried visiting https://rocket.chat/ and arrowing through the page with 
caret mode on, but performance is very slow. I was able to do this under 
Windows/NVDA without issues on the same laptop, so I doubt it's a case 
of my hardware not being up to snuff.

Can anyone else duplicate? Is this at all Orca-related? I don't 
necessarily blame all browser performance issues on Orca but I wonder if 
there might be a pathological case this website may be triggering? It 
does seem significantly less performant than other sites I've 
encountered recently.

Thanks.
