We are discussing the character ]8;; which is the special character OSC.
The terminal emulator should either provide an hyperlink, either do
nothing and ignore what is inside the special character.
As you see, the terminal emulator does not render it correctly.
Setting INSIDE_EMACS turn off that. If it is by default is another story. :-)

However, I thought that it was fixed in Emacs 27. Ouch!

Note that the OSC also appears in some 'guix system' subcommand if I
remember correctly.

You mean set by default, right?

However, note that '*shell*' render correctly the highlighting
(Generation in bold face) so the OSC could be turned off and the
highlight on.



All the best,
