Issue with `unicode-bidi: isolate` use

Steps to repro:

1. Open http://codemirror.net/mode/python/index.html and put this code print('\n'.join(['متن متن', '123']))
2. Add this CSS .cm-string { unicode-bidi: isolate; unicode-bidi: -webkit-isolate; } to your browser CSSs
3. Try to highlight first word on array by double clicking

Actual: You can select the first word. While step 2, fixes the visual issue I’ve describe here, it breaks the editing experiencing I’ve described here

Expected: That CM won’t care about unicode-bidi state, or even better, the CSS mentioned above be added to CM CSSs to help issues like this, in addition to fixing the issue with isolate bidi.

It’d be possible to implement something like this, but I don’t currently have the time to work on it, and as I mentioned, it’d be complicated (the bidi code is already quite scary).

I think also that can be resolved if unicode-bidi is taken into consideration.
