One Way scope binding ('@') is behaving differently since 1.4.1

[phouri]

We recently upgraded to angular 1.4.3 from 1.3.15, (however this bug is when jumping from 1.4.0 to 1.4.1).

I have a scope defined in a directive:

 scope: {
                ngModel: '=',
                mode: '@',
                overallStart: '='
            }

and inside the link function:

 if (!$scope.mode) {
                    $scope.mode = 'daterange';
   }

And in the HTML:
ng-if="mode === 'daterange'"

Everything used to work well, but when changing from 1.4.0 to 1.4.1 I am getting that $scope.mode is undefined, when debugging I see that $scope.mode = 'daterange' is executed, but if I setup a watch on $scope.mode, it's always undefined.

I tried going through the breaking changes, but didn't see anything that reminded of that.

Did I miss anything in the release notes?

I think this a duplicate of a known bug that is scheduled to be fixed in 1.4.4 or 1.4.5: #12290
