Flask-WTF's render_kw does not get applied to melded components for lazy form validation

[cashewpillar]

Using this form,

class RegistrationForm(FlaskForm):
	first_name = StringField('First Name', 
		validators=[
			DataRequired(), 
			Length(min=2, max=15), 
		], 
		render_kw={"placeholder": "First Name*",
					"meld:model.lazy": "first_name"})

the values inside render_kw does not get applied to my final fields after melding with registration form component
