Thanks for the report! There's only one way for a text-mode application, especially one on Linux (or OS X), to change the state of the clipboard on the computer running the terminal. That's to use an escape sequence -- OSC 52, if i recall -- that tells the terminal what to put on the clipboard.

Terminal has never implemented OSC 52, which means that all clipboard modification happens as a result of user action. There's nothing that sudo or exit or your shell can do to change the contents of the clipboard today.

Can you share a screen recording of this happening?
Thanks!

If you are unable to reproduce or unwilling I can't help further. Good luck

I'm willing to reproduce, I just can't. There's nothing in Terminal that knows anything about elevation, especially not over ssh, so I can't even begin debugging this without additional information.
