I don't know how the file is used at all, but the wx code handles this
file being in a .zip, which is essentially the same situation in terms
of seekability (.zip uses the same compression by default as .gz).
This is probably something to do upstream, as being able to have the
same HTML files available for browsing normally seems generally useful.

Well spotted. Yes, the gzip compressor only has a certain window size
in which it can "reuse" text, so sorting will tend to give it more scope
for finding matches.
