I have a select directive with ng-options on a simple array of strings :

<select ng-model="formData.mySelect" ng-options="o for o in ['A','B','C']"></select>

With angularjs 1.2.27, I cannot select the last option ('C') the first time. I can only select other entries.

Reproduced here :

Steps :

• Select the 'C' option of the selection box at first.
• Please note that 'C' is NOT displayed.
• Select the 'A' option of the selection box.
• Please note that 'A' is displayed.

It works well with angularjs 1.2.25.
