When I mute my mic on my local system, why doesn't it mute my mic in Zoom?

I just realized on my Win10 laptop that when I'm in a meeting if I mute my microphone on my local system my mic doesn't show as muted in Zoom.

Why is that?  I'd expect the mic mute status to be in sync between the OS and the application - if the mic is muted in one, it should show as muted in the other.  Whether that's in the Sound Control Panel in Windows or the Zoom meeting.

Does anyone know of a way to get the mic status in Zoom to match that of the OS?
