Go to the Discussion settings in the WP admin panel, enable “Users must be registered and logged in to comment”. Then, under any article that allows comments, you will see the login link, which exposes the new/redirect URL. Not a big deal, but since the URL isnt visible anywhere else on the site, it would be nice to have that scenario covered as well.
I tried with all other plugins disabled and the default theme, no luck. And what’s more interesting, the Classic editor plugin shows the same behavior, so it’s probably something rooted deeper in the core code. Or something specific to project Nami/running WP in Azure. Oh well, figured I’d ask here just in case.
