Hey all,
I was recently validating a page while making some edits and noticed it was triggering a “body seen but an element of the same type was already open" on the page.
Upon digging further it looks like a hubspot form we have for blog subscriptions in the navigation has an input with the ‘Thank you’ message data, right after the submission button but also a seemingly pointless iframe right before the ‘</form>’ closing tag.
Looks something like this:
```
<iframe name=“target_iframe_numbersAndStuff” style=”/* display: none; */">
#document
<html><head></head><body></body></html>
</iframe>
```
Was just wondering if this surved any purpose as nothing about it changes after a submission and it’s triggering a w3 error?
