Webster disagrees and gives dic·tio·nary (https://www.merriam-webster.com/dictionary/dictionary). Since the original hyphen.tex follows mostly Webster, the breakpoints dic-tio-nary are expected. The pattern file was then extended and is called hyph-en-us.tex in modern TeX distributions; it contains the matching patterns 2a2r 2c1t 3dict .dictio5 2io 1na o2n on1a 1tio which, once aligned, yield: 3d i c t .d i c t i o5 2c1t 1t i o 2i o o2n o n1a 1n a 2a2r where we can see that between ‘o’ and ‘n’, a break is first allowed with 1na, then forbidden with o2n, then allowed again with .dictio5. Between ‘n’ and ‘a’, a break is first allowed with on1a, then forbidden with 2a2r. > Is this a hyphe- > nation bug requiring an official exception? Actually ... the word “hyphenation” is consistently hyphenated hy-phen-a-tion by most dictionaries :-) Sadly, both hyphen.tex and hyphen-en-us.tex miss the last breakpoint and yield hy-phen-ation (but hyph-en-gb.tex gives all breakpoints: hy-phen-a-tion).
