Problem with datepicker dateFormat

[HannesHentzschel]

It seems the datepicker is not consistently using the dateFilter to parse the entered dates.

See the following Plunkr:

Its the documentation example except that I changed the dateformat to 'dd.MM.yyyy'.
Now when you change the entered date by changing the textfield using the keyboard the datepicker looses track of the date value. It becomes undefined in the $moduleValue. You can also see that the entered date is not highlighted in the calendar widget.

The reason to me seems to be the use of new Date(stringValue) to parse the date:
https://github.com/angular-ui/bootstrap/blob/master/src/datepicker/datepicker.js#L503

I think is should use the dateFilter like it is done here:
https://github.com/angular-ui/bootstrap/blob/master/src/datepicker/datepicker.js#L540

Ok, the dateFilter is not the solution.
It just converts a date to a string according to the format.
But I need it the other way around.
There seems to be no simple solution for this.

But I really think the datepicker should parse the modified input contents according to the format in the datepicker-popup attribute.
