Google OAuth API not working anymore?! 404 error

Question

I've got a strange problem with my Analytics Windows Phone App. It's been 2 months now from the first release. My Google Oauth always worked... until several days ago.

It is impossible to authorize the app to access Analytics data anymore. And I've changed totally nothing!

The first URI I use is:

 https://accounts.google.com/o/oauth2/auth?redirect_uri=http:// localhost
 &response_type=code
 &client_id=*myClientAppId*
 &approval_prompt=force
 &scope=https://www.googleapis.com/auth/analytics.readonly
 &access_type=offline

It's the same as https://developers.google.com/oauthplayground/. The Web Explorer shows me the login form, and then the authorization form. When I tap "Authorize access", it redirects me to a 404 page.

I don't know why, it always worked before.

EDIT: OK, this works in Google Chrome. It gives me a 404 at the end but the code is in the browser URI.

EDIT 2: It works in Firefox too! But not in Internet Explorer. Google has modified something that doesn't fit IE! As it is IE in Windows Phone, I'm out of luck.

EDIT 3: This is the URL from Windows Phone IE during the process:

https://accounts.google.com/o/oauth2/auth?redirect_uri=http://localhost&response_type=code&client_id=*clientID*&approval_prompt=force&scope=https://www.googleapis.com/auth/analytics.readonly&access_type=offline

404 error -> https://accounts.google.com/o/oauth2/

On Chrome, same URIs, but when I click on "Authorize", I get localhost with the code for the token.

I believe in WP, embedded IE webview has javascript disabled by default. There's a simple webview API call to enable JS before starting the webview. At this point, we can only reproduce this bug in browsers that do not execute JS.

More specifically, see: http://msdn.microsoft.com/en-us/library/microsoft.phone.controls.webbrowser.isscriptenabled(v=vs.92).aspx on how to enable JS.
