Description

Single sign-on was fine with ABP version 5.3.5, but when I upgraded to 7.4.5, The SignOutIframeUrl was normalized to / causing single logout failure.

Reproduction Steps

Create a new tiered template project that includes a web client, add a angular client for single sign-on, log in to both the web and angular clients, log out of one of them, refresh the other client to see that it is still logged in.

Expected behavior

The SignOutIframeUrl is a normal URL rather than a /.
