The theory is that terminals should ignore OSC codes that they do not
support.  Good’ol xterm, for instance, silently ignores those hyperlink
codes, whereas GNOME Terminal interprets them nicely.

So I would say that this is a bug in this version of mate-terminal, or
perhaps in the libvte version it’s using?

I’ve just tried mate-terminal 1.22.0 on vte 0.58.3 from Guix, and it
silently ignores those codes.

Thanks,
Ludo’.
