ng-option doesn't handle first selection properly under IE11

[TimotheeJeannin]

Selecting an option for the first time in a select dropdown under IE11 when no option is currently selected

• does not make the select dropdown display the correct option
• does properly set the selected option value in the model though

Reproducible: alaways

Browsers: IE11

Operating system: Windows 7, Windows 8

Steps to reproduce:

• Go to this plunker http://plnkr.co/edit/XWXhqupzPItuLT3KUvPq?p=preview using IE11
• Click on the select dropdown to open it
• Click on the second, third, fourth or fifth option
• See the select displaying first instead of the selected option

or

• Go to the AngularJs doc with IE11 https://docs.angularjs.org/api/ng/directive/select
• Scroll down to the last example
• Click on -- choose color -- in the dropdown next to Color (null allowed):
• Click on red in the dropdown next to Color (null not allowed):
• See the select displaying black instead of red

What I'm seeing is:

The model value IS actually being set correctly, HOWEVER

For the first selection, the incorrect option appears to be selected in the view. But for subsequent selections, it seems to work as expected

This is reproducible

Seems to be a regression introduced in v1.3.0-beta.3 (http://plnkr.co/edit/jCt2PBLmwmAzStgjJa69?p=preview), probably by f40f54c / dc149de

This also affects IE10 and IE9

Angular 1.2.15 and 1.2.16 seem to be affected too. (http://plnkr.co/edit/VePYsd7TO1qPoVoxUJji?p=preview)

Works fine with Angular 1.2.14 and 1.3.0-beta.2 though.

Yeah. Do you have access to a native windows machine @TimotheeJeannin? If you do, do you want to try to work on a fix for this?

I can try later in the week, but I don't have a native windows machine, so it's a bit trickier for me, and I'll be a bit occupied.

We should definitely fix this asap.

I do have access to a native windows machine and may be able to work on a fix.
It's 5:30 pm here, I may be able to submit something tomorrow morning.
