Duplicate submissions with inline confirmation and reference fields

Problem/Motivation

When a webform is set to Inline (reloads the current page and replaces the webform with the confirmation message)
and it is in a reference field submissions are duplicated.

I think each reference layer duplicates the response.
Webform reference on node = 2 emails
Webform reference on paragraph on node = 4 emails

This occurs when Inline (reloads the current page and replaces the webform with the confirmation message) is the confirmation mode. Changing to Message (reloads the current page/form and displays the confirmation message at the top of the page) fixed the issue for us

Steps to reproduce

Modules:

• webform 6.2.7

Webform configuration
Create webform with 1 field

• Text field

Change confirmation to Inline (reloads the current page and replaces the webform with the confirmation message)
Add message in Confirmation Message field

Add one handler
Email to the submitter
Default email settings

Content settings
Add webform reference field to basic page
Add basic page and choose the webform you created.

Receive duplicate responses
Submit the form, you will receive multiple responses.
This happens in production and in ddev locally.

Important notes:
If you have a paragraph the duplication is doubled from the reproduction steps.

If you use the test function OR visit the view tab for the form and submit from there you will NOT receive duplicates
Changing the confirmation type from INLINE to Message (reloads the current page/form and displays the confirmation message at the top of the page) also stops sending duplicates.
