Trix: Broken in Win 7/IE10: Unable to set property 'trixSelection' of undefined or null reference

Check out this screenshot from browser stack.

This issue arises on trix-editor.org, as well as the locally hosted version of trix we use on our site. The console message is as follows:

SCRIPT5007: Unable to set property 'trixSelection' of undefined or null reference trix.js, line 20 character 22130

Nevermind -- just saw that you don't support IE10, which is a bummer. We love your plugin, but our business still requires support down to IE9.

The error can be fixed by adding a dataset polyfill - https://github.com/remy/polyfills/blob/master/dataset.js

This doesn't actually make Trix work on IE10 (outside of basic input) but you can load the script without it failing which may be useful for some.

@javan Do you have a high-level idea of what might be needed to support IE10? That's the only thing keeping me from using Trix, and I may try tackling IE10 support if it's not too much work.

@jdrorrer I'm honestly not sure. @tedtate's comment above is a good starting point. Trix will never officially support IE10 so adding polyfills to your app is the safest route.

@javan okay, thanks!

The JS on my app is not working anymore because of this issue when opened with IE 10 or lower. I understand that supporting IE10 is out of question, but it would be great if trix just did nothing if opened in an unsupported Browser, instead of causing an error.
