[Support request] Delete account page is showing on “error page” instead of current theme page

Hello.

I am working on user profiles and if user want to delete his account, the delete page is not showing on the current set theme, but instead on the error-page which WordPress is using for showing errors, so without any headers, footers etc. Is showing in <body class=”error-page”>

There is two major issues with this:
1. You can’t customize this page with own css or js
2. You can’t translate this page, even if in “account_delete_warning.php” are used the translation strings

Is there any special reason, why delete page can’t be shown in theme?

Thank you
