Incorrect answer to "Contact owner" robot question results in unhelpful "Validation Error" banner

What steps does it take to reproduce the issue?

• When does this issue occur?

When contacting the owner and incorrectly answering the question for "Please fill this out to prove you are not a robot."

• Which page(s) does it occurs on?

Any dataset record page.

• What happens?

In the modal, a helpful message appears

Incorrect sum, please try again.

On the main page behind the modal, A banner appears with the text:

Validation Error – Required fields were missed or there was a validation error. Please scroll down to see details.

• To whom does it occur (all users, curators, superusers)?
  All users

• What did you expect to happen?
  I'd expect the error message in the modal to appear as it does now, but the banner is confusing. I'd either expect it not to appear, or to have a more helpful message.

Which version of Dataverse are you using?

Reproduce the issue from any dataset record page by opening Contact owner and submitting an incorrect robot-answer response. Trace how the modal's “Incorrect sum” message and the main-page validation banner are handled. Done means the helpful modal message remains while the confusing banner is removed or made specific to the failed response.
