No confirmation message when registration settings are saved without changes at Special:RegisterForEvent/xyz

When an event is registered through a direct registration link, the system displays the following message:

"Your registration information was updated."

However, when a user opens the registration link again and clicks Save after reviewing the registration visibility setting (Private/Public):

• If the user changes the setting and saves, the message "Your registration information was updated." is displayed.
• If the user clicks Save without making any changes, no message is displayed.

This can be confusing for users because there is no indication that their action was processed successfully.

Suggested Improvement

• Display a confirmation message whenever the Save button is clicked, even if no changes were made.
• Alternatively, display a message such as:
  • "No changes were made to your registration settings."
  • "Registration settings saved successfully."
