I haven't checked the character ： before **123, but it is likely considered as a space or unicode punctuation character and so, as stated by the spec, the right ** is not going to be detected as a right flanking delimiter run.

A right-flanking delimiter run is a delimiter run that is (1) not preceded by Unicode whitespace, and either (2a) not preceded by a Unicode punctuation character, or (2b) preceded by a Unicode punctuation character and followed by Unicode whitespace or a Unicode punctuation character.

Almost all CommonMark implementations are reporting the same (only one is showing strong, but I believe it is invalid)
