You can copy/paste from different browsers..

seems to be persisted in the MG database on a user session basis instead of a user basis!?

I am not sure. But I have successfully tested it right now.
I logged in in two different browsers (Chrome and Firefox on a Mac) with the same account. I could copy/paste modules from different racks.
You hover the mouse over one module in the first browser and press c than go to the other browser, hover with the mouse over the rack (important) and press v. No CTRL, no CMD, no ALT, just the keys c and v.
Keyboard Shortcuts must be enabled, Rack Lock must be disabled.
This does not work for you?
