Very interesting. Chrome does appear to have some significant caching
problems as well as a rather idiosyncratic approach to HTML. Possibly
not coincidentally, this was noted by some speakers and delegates at the
annual XML Summer School in Oxford the week before last, so it does seem
to be a thing. I hope they fix it, because I'd hate to have to go back
to FF since I deleted it from my systems.
