Win10 Snap not working for RemoteApp streamed apps

Hi there. We use AVD for streaming RemoteApp published apps from Win10 Multi-user VMs in Azure, using the MSRDC client. We discovered that Win10 Snap features, such as Windows key + left arrow, to snap a window to the left half of the screen, is not working. Windows + up arrow and Windows + down arrow works however.

Works just fine when using a traditional Windows Server 2019 Remote Desktop configuration to publish RemoteApps and using the MSTSC client, so we were surprised to see this not work with AVD and MSRDC.
