Bug

What is the expected behavior?

When clicking the calendar icon to open the datepicker it should open the same md-datepicker container every time.

What is the current behavior?

Every time you click the little calendar icon to open the datePicker it creates another md-datepicker container wich results in multiple md-datepicker containers and the last one with the actual calendar.

What are the steps to reproduce?

1. Open the datepicker
2. Close the datepicker
3. Re-open the date picker
4. See the duplicated MdDatePickerContent with Augury Chrome plugin.

I'm not seeing that behavior on the demo site when inspecting the DOM:
https://material.angular.io/components/component/datepicker

[icampo-cic]

The demo site can't be inspected with Augury since it is in production mode. It isn't a visual issue, you can only see it in Augury.

@icampo1103 Yeah, I'm seeing it in the memory profiler
