Hubspot form too tall when in mobile mode

Hi all,

I have a HubSpot form on my page that works just fine when the screen is full-sized.

But when the screen is in mobile mode, the HubSpot form behaves responsively as it should, but the HubSpot element is too tall for the group and drops into the next element below:

You’ll notice where the submit button sits:

Ideally, the group holding the hubspot form increases in height as the HubSpot form increases in height. Any ideas?
