5.23 breaks WP admin menu links

In looking at financial#120 (closed) I came across a regression, possibly related.

Starting with 5.23 (and also present in 5.24 RC) in WordPress:

Go to any any CiviCRM page for example /wp-admin/admin.php?page=CiviCRM&q=civicrm%2Fcontribute&reset=1
Look at the url in WP sidebar for 'Dashboard'
The dashboard link is showing as https://example.org/wp-admin/admin.php/index.php
The link should be https://example.org/wp-admin/index.php
the WP menu is built with just index.php so the menu is picking up the extra admin.php from CiviCRM.

This issue is not in 5.22
