After quite a bit of fiddling, it turns out RFC 768[1] has a trailing
form feed character (^L). If you remove this (invisible) character after
"Postel [page 3]" at the end, it should work.
TiddlyWiki's formatter should probably not get confused by this. I'll
raise a ticket.
By the way, it would be helpful if you could include relevant
information like the RFC link or even a test case[2] next time.
