Form submit on change not working for date type

[tim-x-y-z]

The form object doesn't submit when date is changed. This makes it hard to use date in inline forms.

class FilterForm(pydantic.BaseModel):
    country: str = Field(json_schema_extra={'search_url': '/api/forms/search', 'placeholder': 'Filter by Country...'})
    date_tung: date = Field(title='Date Tung', json_schema_extra={'format': 'date'})
[...]
        c.ModelForm(
            model=FilterForm,
            submit_url='.',
            initial=filter_form_initial,
            method='GOTO',
            submit_on_change=True,
            display_mode='inline',
        ),
[...]
