Don't copy-paste commands from webpages – you can get hacked

I tried the example on the linked PoC page...it didn't work. I literally got what it showed visually, no newlines or other unexpected stuff: sudo apt update

Watched console while doing it, and didn't see anything at all (was expecting some js error or something).

For those that are wondering...Firefox 95.0.2 on Windows 10

I hadn't really thought about the possibility of malicious contents being written to a clipboard after the fact. There goes another item on the huge pile of things that might seem ok on the surface, but can completely F you.
