Comment 3 for bug 849416

The problem is how Mozilla decides which part to display, and which part to
hide. Is there some standard that says use first recognizable and ignore the
rest? or is it an internal design decision for Moz?

If I install a calendar plugin, can that plugin tell Moz to utilize
text/calendar; types instead of text/plain; types? (If so, maybe I need to log
this bug against the calendar/sunbird project, because they are not doing it.)
