Preview broken for entries in Pages Module

Testing with 2 different EE 5.3.0 installs it seems the Preview in the edit entry screen in the CP doesn’t respect the ‘Preview URL’ set in the channel settings.

You can set any old nonsense path in the Channel settings for the preview template and it makes no difference, it will still use the same template used to render the page as specified in the Pages module.

I’m assuming this is some quirk of the Pages module and the way it handles URL’s so it’s maybe overruling the preview template URL?

The preview works fine in a channel that isn’t associated with the Pages module so I’m pretty sure it isn’t just me.
