Tracking with noscript and other domain



thank you very much for coding Matomo.

I try to track with noscript img tag on a different hostname than url to track.
With globally enabled javascript everything works fine.
What happens if the user enables the “main hostname” with a noscript / umatrix addon in such a way that the matomo server is still disabled?
I think the browser thinks noscript should not be rendered because of allowing the main hostname scripting support.
Has anyone an idea how to track anyway?

Thank you.
