Compatible with remix optimistic updates?

[setvik]

Prototyping with remix-hook-form together with optimistic UI in remix, but navigation.formData doesn't appear to populate until after the server responds (instead of immediately upon form submit).

Anyone have thoughts as to why and whether this can be fixed?

i.e. if i add the following to the route component containing the form, I would expect it to console.log the submitted form data as soon as i click submit, but instead, navigation.formData isn't populated with the form submission until after the server responds (e.g. the action finishes executing).

const navigation = useNavigation();
console.log('NAVIGATION FORM DATA', navigation.formData && Object.fromEntries(navigation.formData));
