Dynamic Scaling not working when double-clicking *.rdp file

I'm using Microsoft Remote Desktop Version 10.8.3 (2098) on macOS 12.2.1.

When I explicitly add a server via the "Add PC" dialogue (which has the 'Update the session resolution on resize' option ticked by default), dynamic scaling works as expected.

However, if I launch a remote desktop session by double clicking an *.rdp file, dynamic scaling does not work. This is true even when the *.rdp file was created by exporting a previously created "PC", for which dynamic scaling worked, when the session was launched from *within* the Microsoft Remote Desktop app.
