Quick summary

When building a form, if you add any field that takes one or more choices (multiple checkboxes, radio buttons, dropdown), make that selection required, but don't add any options to choose from, the form becomes unusable. There are no options to select for the required field, but instead of showing an error about missing required fields, the form appears to submit and redirects to a 404 error.

Only tested so far on Dotcom Simple. Initial report in 9436738-zd-a8c.

Steps to reproduce

Steps to reproduce

1. Create a new page.
2. Add the Form block, select any of the predefined options (e.g. contact form).
3. Add a new block into the form: Single Choice (Radio), Multiple Choice (Checkbox), or Dropdown Field.
4. Select the parent of the block that was just inserted (if needed) and mark it as required. Do not add any options to choose from.
5. Save the page.
6. On the live page, note that this block isn't visible, as there are no options to choose from.
7. Fill out the form and submit.

<!-- wp:jetpack/contact-form -->
<div class="wp-block-jetpack-contact-form"><!-- wp:jetpack/field-name {"required":true} /-->

<!-- wp:jetpack/field-radio {"required":true} -->
<div class="wp-block-jetpack-field-radio"><!-- wp:jetpack/field-option-radio /--></div>
<!-- /wp:jetpack/field-radio -->

<!-- wp:jetpack/field-textarea {"label":"Message"} /-->

<!-- wp:jetpack/button {"element":"button","text":"Contact Us","lock":{"remove":true}} /--></div>
<!-- /wp:jetpack/contact-form -->

What I expected

For other required fields, an error is shown letting the submitter know that the field is required (Please fill out this field. / Please make sure all fields are valid. You need to fix x error(s).). There should be a similar error in this instance as well.

Ideally, it should be impossible to save a form with an invalid multi-input like this, especially if it's marked as required.

What actually happened

The form appears to submit, but redirects to /?page=1#contact-form-{page-ID}, which doesn't exist (error 404).

If a workaround is available, please outline it here.

Removing the offending block, marking it as not required, or adding 1 or more options to choose from fixes the issue.
