[BUG] Multipart error when submitting with empty form-data

[phihung]

Error when submitting a multipart/form-data form without any data

Minimal Reproducible Example

@rt("/")
def home(): return Form(Input(name="a", type="checkbox"), Button("Submit"), hx_post="/process")
@rt
def process(x: dict): return f"Check box is {x.get('a', 'off')}"

Click on submit (without ticking the checkbox)

multipart.exceptions.MultipartParseError: Did not find CR at end of boundary

Workaround: Change Form.enctype

Form(..., enctype="")
