Volume camera's OnWindowResized event not being called when system zoom setting called

I want my content to remain at a consistent scale compared the real world in mixed reality, but when users change the system zoom setting in display, my unity content is getting bigger and smaller, whether I’m in MatchWindowSize or ScaleToFit using the VolumeCameraResizeListener, pretty much exact same behavior either way. So I put some debug logs in there and OnWindowResized just isn’t firing when the system zoom setting is changed.
