Vector is all sorts of broken on mobile web

[ara4n]

In no particular order:

• Incredibly slow and unreliable at changing rooms
• Lets you scroll off the bottom of the screen
• Doesn't resize when keyboard is visible
• Need to change the zoom to be more legible in general
• Autofocuses the input box too often, rezooming everything
• Hoverovers get stuck on
• Doesn't default to hiding membership list (on 6+ at least)
• Flexbox bug on iOS 9.2 means invite box overlaps the membership list
• Scrolling to bottom of the timeline doesn't make it all the way
• Avatars overlap (general Safari layout bug potentially)
• doesn't progressively load (bundle.js is enormous #126 aka bundle.js is way too big and should progressively load to speed up initial launch #2498)

I fixed most of these for angular already; it's just a matter of porting over similar fixes.

Do we still want this?

@lampholder I'm pretty sure we can close this because of the mobile landing page...

Works for me. There's an app for this, I've heard :P

i’m not entirely sure we should close this one tbh; we need to make Riot more of a PWA, and a good indicator if whether we have is if it runs on mobile. At least, this was my motivation...

I think we would need to very consciously choose to support mobile web and invest in making it work for there to be any chance of it working well as each new feature lands over time. (To be clear, I think it would be great to support this! I just want to call out the level of investment required.)

If we're not in a position to support mobile web now, maybe we leave this closed until we are. (After all, I would likely also close issues that only happen in ancient desktop browsers we don't support, since they are outside our supported set.)
