Issue with close button in Customizer

Hi.

I have installed Weaver Xtreme in subfolder my-domain.com/site and having a minor issue in the Customizer.

Normally when pressing the X (close) button in the Customizer it should redirect me to the previous visited page in my dashboard.

When I press this button after setting or changing the “Options Level and Interface”, it redirects me to main dashboard page /wp-admin, but the subfolder site is not taken into account. So it redirects me to my-domain.com/wp-admin, which causes a 404.

I don’t know whether this is a WP thing or something you can fix?
