Looks like it’s specifically when an underscore follows a normal letter instead of whitespace. Not sure if that’s as intended by the markdown spec, incorrect in Voyager or unspecifed
With underscores:
normal_italics_ normal italics
With asterisks:
normalitalics normal italics

That’s almost certainly intended behavior, otherwise any underscore would trigger formatting (much like the asterisk does instead of allowing snake_case_naming

The markdown specification recommends using asterisks specifically for that. It is not exactly intended, but left to the interpreter. Most markdown interpreters leave the underscores intact if they’re inside a word.
