Street View Icon missing/blank

I’ve configured the WP Google Map Plugin to the best of my knowledge – and everything seems to work just fine. The only exception is the Street View function.

When I enable Street View, a white square appears on the map – but without the usual orange/yellow person icon.

Could this be a bug?

When I drag the white square onto the map, the icon appears and the map opens Street View of the street where I placed the icon. So that part works OK.

I’m running WP 5.8.0 and my plugins are all up-to-date.
