FWIW, I've seen this type of behavior repeatedly.  I think the wiki
webserver is allowing the browser to cache the old copy of the page.
If you don't have it in cache to start with, or after the cache copy has
expired, you won't see any inconsistency.

There was a thread about this awhile back which suggested that the
problem was http: vs https:, ie if you first visit a page non-secured,
and then log in, the server switches you to https: but the browser
doesn't realize that's the same as the http: page.  I tried to address
that by changing all my wiki bookmarks to https:, but I think I've still
seen the behavior since then.
