Confirmation message does not appear in modal when per user submission limit is set to 1

Problem/Motivation

Confirmation message does not appear in modal when per user submission limit is set to 1

Steps to reproduce

1. Create a webform
2. Set the Submission limit setting as follows.

3. Select Confirmation type modal and fill it as follows.

4. The modal will not appear when you log in and fill out the form with a non-role user.

Proposed resolution

In the code, webform limit operations are performed in the getCustomForm function. Since the form comes from here, the code does not continue until the lines that trigger the modal. The modal must be triggered before this function.
