Thank you for adding this issue, @okmttdhr

I tested a few other Block themes and saw that the Customizer was showing up for several of them.

I suspect that this is related to ‘Untangling Calypso’, such that site specific screens default to WP Admin style screens. This means that seeing ‘Customizer’ in the dashboard when using Block themes is normal.
