Public bug reported:

When the calendar widget is used on a field that is displayed in a
modal, the widget displays behind the modal so you can't see it.  None
of the fields that use a calendar widget is currently displayed on a
modal so this has not been an issue.  I encountered the problem when
extending horizon with a custom panel that uses a modal with a calendar
widget on it.

To recreate, the datepicker must be initialized on modal init, and a
date field needs to be added to a modal form.  For example I added the
following fields to the Admin -> Create Network form.  The datepicker
init code keys off the start and end field IDs so it's easiest to just
use those names.

    start = forms.DateField(label=_("Start date"), required=False,
                                 input_formats=("%Y-%m-%d",),
                                 widget=forms.DateInput(attrs={
                                     'data-date-format': 'yyyy-mm-dd'}))
    end = forms.DateField(label=_("End date"), required=True,
                          input_formats=("%Y-%m-%d",),
                               widget=forms.DateInput(attrs={
                                   'data-date-format': 'yyyy-mm-dd'}))

Initialize the datepicker on modal init somewhere in the javascript:

    horizon.modals.addModalInitFunction(horizon.forms.datepicker);

When you open the Create Network form and click in the Start date or End
date fields you can see the calendar partly showing underneath the
modal.
