WP8.1 IE11 not updating

[thorerik]

I have traced the issue down to be related to Enhanced Protection mode that is, by default(and not possible to disable afaik), in Windows Phone 8.1.

Issue can be replicated by setting IE11 with these settings or by using the F12 menu and set emulation mode to Browser profile Mobile.

Adding

<meta http-equiv="X-UA-Compatible" content="IE=edge;" />

Does not fix the issue either(though should be in there).

My Javascript knowledge isn't that great, but what I've been able to find is that setTimeout() call is handled differently in protection mode, but I'm not able to confirm or refute it with any kind of documentation or google-fu.

edit: ref this microsoft page, it might be possible to emulate the issue using metro browser as well

latest commits don't fix the issues, X-UA-Compatible needs to be moved up to make scripts run, but it isn't enough to fix the WP8.1 issues.
