Django: Crispy forms on django-filters removes selected on drop-down lists

Question

Why does | crispy remove the selected attribute on drop-down lists of my filters? It does not show the currently applied filter.

Given the following forms.py:

class TaskListView(LoginRequiredMixin, ListView):
    model = Task
    paginate_by = 10

    def get_queryset(self):
        # all groups for user
        groups = self.request.user.groups.values_list("pk", flat=True)
        groups_as_list = list(groups)
        queryset = (
            Task.objects.filter(object__owner=self.request.user)
        )
        return queryset

    def get(self, request, *args, **kwargs):
        filterset = TaskFilter(request.GET, queryset=self.queryset)

        self.object_list = filterset.qs
        context = self.get_context_data(filter=filterset, object_list=self.object_list)

        return self.render_to_response(context)

And filter.py:

from .models import Task
import django_filters


class TaskFilter(django_filters.FilterSet):
    class Meta:
        model = Task
        fields = ["status"]

I'm calling the following URL: http://localhost:8000/task/?status=30

With {{ filter.form }} the template generates the following output:

<select name="status" id="id_status">
  <option value="" >---------</option>
  <option value="10" >Overdue</option>
  <option value="20" >Due</option>
  <option value="30" selected>Pending</option>
  <option value="40" >Inactive</option>
</select>
...

With {{ filter.form | crispy }} the template generates the following output, which is missing the selected value:

<select class="bg-white ..." name="status" >
  <option value="" >---------</option>
  <option value="10" >Overdue</option>
  <option value="20" >Due</option>
  <option value="30" >Pending</option>
  <option value="40" >Inactive</option>
</select>

Any idea why the selected is no longer in place and the id="id_status" is gone?
