Clipboard not working in Linux using Microsoft Virtual Desktop Cloud Regions with MS Edge

The new Cloud regions don't support forwarding the clipboard: when I click to to select the region, it just says I can forward the camera and mic, no clipboard. And, of course, the clipboard doesn't work.

When I use the now called "legacy regions", the clipboard is forwarded and works. That is the main reason I use those, as the clipboard is essential for my work-flow.

This is using Linux, with latest edge browser.
