Figma Make to Figma Design bug?

Hi there,

We’re trying out the new Figma Make ‘copy design’ feature, to move a Figma Make output to a Figma Design file, but while the copying step looks fine, when pasting into the design file, the output is all just text output (as below)?

The only weird thing I noticed was that in the launch videos for this feature, it shows Figma Make displaying a message: ‘Copying as design layers’ 

...but i’m not seeing that - it’s just shows ‘Copied design to clipboard’ - maybe this is a bug? A colleague suggest it works on Safari, but not working for me on Edge, maybe is a browser thing?
