I did nothing special for it, so it seems the default feature.
In my case the cache is stored in the file:

~/.emacs.d/url/cache/yamaoka/https/org/gnu/debbugs/251a7740923b0757bb1cd2b95e60bf88

Removing it manually vanishes the "Not modified" error.

Could you try exiting the ephemeral bug group by `q' before
retrying it?  Though I can reproduce the error without doing so.
