Keyboard doesn't tunnel properly through Remote Desktop

I'm remoting into my work computer through the Azure Virtual Desktop website. And then in the work computer, I'm using Acronis to remote into a mac. The keyboard will not go into the Acronis session, but the mouse works fine.

When I use the Remote Desktop application, the tunneling works fine into the Acronis session, so I know it's possible. There's a bug in the web version.
