Fix appearance in IE 9

I had the styles working well in IE 9 (which cannot use flexbox) until a short while ago, when something apparently broke it.

@fritz-c No sure if IE 9 support is really necessary given decading IE 9 usage. Lack if flexbox support makes this quite complex.

Technically, IE 9 has extended support until April 2017. It's because Vista extended support ends then, and IE 9 is the latest version you can get on that. I even have that date set on my personal calendar (Unofficial Start of Flexbox Day).
I'm not aiming to make it work perfectly, but I actually had the positioning working pretty well before I put in the flexbox stuff. It shouldn't take much to get it back to that state again.

Anyone have insight into what was the last version in which IE9 still worked?

Unfortunately my team still has to support it so, +1 for fixing it in IE9.

@topher515 I got the basic appearance working on it with v0.1.4, but in my tests (on a remote machine) the performance was less than spectacular, and the landing pad (the blue / red area displayed when hovering) wasn't displaying for some IE reason. Usability-wise, I don't think anything's broken beyond use. It's just not great.

You can add support using flexibility polyfill

@enniel Thank you for the suggestion. However, as the end of support for IE 9 is only a couple months from now, and I haven't had too many requests concerning it, I think I'll be leaving the IE 9 compatibility as-is.
