Windows Phone 10 / IE 10 bugs with displaying opt groups with ngOptions

[likesjx]

Windows Phone browser object will not display the contents of the opt group without a non-empty value. Any opt group created by ngOptions will not be displayed.

Will windows phone display angular apps at all? there have been a lot of issues reported with WP8 due to unsafe DOM manipulation being used, so it's possible that the actual problem is something else?

The app displays fine and has been in production for some time now.

But here is some additional information that we've found:

We've tested this out with just html and it seems to work. We've tried to add it to the creation of the optgroup template but unsuccessfully.

Can you please provide an example? I happen to have a Windows Phone which runs IE11 (although there are no debugging tools ...) Does it happen on IE10 and IE11?

It happens only in IE10 and IE10 mobile (but apparently specific builds). The funny thing is that it works in our web application using the native browser but not when using the browser object inside of an native application. But we have been able to reproduce this issue with IE10 desktop and IE10 mobile.

Has there been any movement around this? you can try m.att.com and try paying your bill...

Now that's an interesting comment.
So I was actually able to reproduce this in IE10. It seems to me that this is a pretty low-impact bug, as most people will disable browser form validation when using angular.

Closing as low frequency bug. As a workaround, a regular select can be used.
