You can create a javascript hook, react on form submit event and do this via javascript

<script>
MsCrmMkt.MsCrmFormLoader
.on("afterFormSubmit", function(event) { 
  const elements = document.getElementsByClassName("onFormSubmittedFeedback");
  for (let i = 0; i < elements.length; i++) {
    elements[i].style.height = "auto";
    elements[i].style.width = "auto";
  }
})
</script>
