Yeah, that's true.  I've now reopened this bug report.

If the base document is fetched via Tramp, then relative links to
further documents via Tramp isn't a security concern at all.

I'm just wondering on what level this should be fixed at.  eww could add
further support for these relative links itself, or the url-file.el
library could grow some overrides to allow following Tramp file
names...  Hm...  The latter seems easier to implement, but I feel that
perhaps the former is what makes most sense.
