FYI, I find it hard to follow an issue when folks edit descriptions and
comments.
I think the best practice is to submit issues whose description briefly
describes the problem. Then comments can be used to elaborate on the
problem and develop a solution. If one changes one's mind, one should
add a new comment noting that, rather than editing a prior comment. If
the initial description is no longer accurate, file a new issue, close
the initial issue as "won't fix" and link it to the new issue.
I've noted this before in the HowToContribute page:

Similarly, there is no need to remove stale attachments. These provide
history and are useful.
Thanks,
Doug
