I have added a second form above the first form it is titled Arbitrary Radio Buttons and has 2 radio inputs. The form below also has radio inputs. The non hubspot form radio inputs work as expected but the form inputs wont release/reset the radio inputs.
This is the code that unsets the regular radio inputs.
I have come across issues like this in the past - though I can't remember off hand what the solution was (it was a while ago). Probably has something to do with how the HubSpot form(s) are rendered and mounted via React and how it keeps track of the state of the forms input values if I had to guess.
