attrs.$observe does not work if ng-options is attached to element

[romario333]

I have test directive which accepts interpolated value:

<select ng-options="item for item in items" ng-model="selectedItem" test="hello {{selectedItem}}"></select>

test directive uses attrs.$observe to watch for changes of interpolated value. After upgrade to 1.2.0-rc.3 this no longer works (I get non-interpolated value). In 1.2.0-rc.2 it works ok.

Note that this bug seems to be very similar to issue #4525 and #4528
