Incorrect date input style when it is disabled

[jmaister]

When a date input has the disabled state, the background is not changed.

The problem comes from the datepicker.html:

<input ng-show="form.key"
       style="background-color: white"

Even if the component is disabled, the background color keeps as white, instead of changing to CSS classes ".form-control[disabled], .form-control[readonly], fieldset[disabled]"

This issue no longer applies from what I can tell, the code now uses a class name and no inline styles.
