Apologies for the issue, I can definitely make a bug request for this and a feature request for added style options to be consistent with other components.
For now, a workaround seems to be that you can click to drag to expand the textarea to the size needed.
Strong +1 for this. The workaround is not really great because it introduces training for staff and higher margin for human error (because information is not seen at first glance).
This will work for now until our engineers can get their hands on this ticket. I will post with any updates I hear from the team as I was working with them yesterday on this issues so we should hopefully see some traction shortly.
