So, ua-parser isn't actually being used for our frontend at the moment.[0]
That's, I think, a Timo Problem (yay! :P).

In terms of ua-parser generally and its application to analytics
specifically, the example user agent reports as Chrome - which is
unsurprising given that the user agent doesn't actually identify as IE. I'm
going to write a patch for ua-parser now and, assuming it passes the tests
and gets +2d, that'll solve the problem for post-hoc analytics. But, for
the sake of every user agent-y person on the internet, please consider
coming up with a user agent that actually explicitly identifies the
browser.[1]

[0]We actually have three different user agent parsing solutions - one for
site determination, one for feature determination, and one for post-hoc
analytics. I'm pushing the ua-parser team towards building a cacheing layer
and then hoping we can look at using ua-parser in production, thereby
standardising: we'll see.
[1] http://webaim.org/blog/user-agent-string-history/ should be confusing,
not comedy.
