------------------------------------------------------------

[~steunix], a couple of things. As described in the comment here, the paste 
action has been removed from the context menu for specific reasons. However, 
CMD+V (or CTRL+V on windows) does still paste copied content.

As far as the console error you are seeing, I can't seem to reproduce this in 
the 2.2.0 release or in the current main branch. Are there any more details 
that you can provide? Chrome version, security model (HTTPS/HTTP), type of 
processor you are copying, permissions/policies on the processor, anything else 
that you may think relevant.

> Hi,
