Description

1. Add a DatePicker to a DateTextField.
2. Add the DateTextField to a WebMarkupContainer.
3. Set the WebMarkupContainer's visibility to false.
4. Load the page.

Notice JavaScript error (this.oDomContainer is null: calendar.js, line 1452).

It looks like the header contributions for the calendar are being rendered even if the calendar itself is hidden.
