Not A Bug Mutate creature blocks intimidate creature

[HartshornN]

This just happened in a game I was playing for PD League (event ID 254148042). My opponent mutated a parcelbeast onto a coiling oracle during my attack phase and afterward was able to block my immerwolf (intimidate creature). I think MTGO considers the mutated parcelbeast to be 2 creatures for the purposes of blocking. This feels like it will be a niche issue due to the lack of players playing mutate creatures, but it should be simple enough to reproduce.

this is how the game is supposed to work. Intimidate reads "This creature can’t be blocked except by artifact creatures and/or creatures that share a color with it." and parcelbeast/coiling oracle shares a color (green) with it
