Logout not working with subdomains

I’m getting an error when logging out using wildcard subdomains. I noticed in old docs there is a setting under migrations that looked like it would fix it (allowing anything for logout) but I can’t find it anywhere in the current UI.

In my application settings, I have this set:
Allowed Logout URL’s: http://*.localhost:3000

I’m getting this error when logging out:
The “returnTo” querystring parameter “http://brite-smiles.localhost:3000” is not defined as a valid URL in “Allowed Logout URLs”.
