Describe the bug

On the sample project: spring-security-samples-boot-oauth2-integrated-authorizationserver-custom-consent-page, upon landing on the custom consent page, the 'Cancel' button does not submit the consent form, but rather clears all form elements, as it is set to type=reset. This issue also extends to the default consent page as defined in OAuth2AuthorizationEndpointFilter class.

Looks like the specific change was introduced in commit 7b4fc46

To Reproduce

1. Launch module: spring-security-samples-boot-oauth2-integrated-authorizationserver-custom-consent-page and adjacent sample client and resource server
2. Navigate to sample client (localhost:8080)
3. Log in with user1 and password
4. Be redirected back to sample client home page
5. Click on authorization code grant type
6. Be redirected to Consent page
7. Click on 'Cancel' button

Expected behavior

The form is submitted and user is redirected back to client with no scopes approved.
