Bow animation error in multiplayer

While playing with other player (crossplatform between Windows 10 and Pocket Edition) I have seen weird animation bug where bow's string pulling pose was visible all of the time.
I am not sure what is the reason of this bug, but it mostly happened to other player, who uses bow a lot and I had noticed it sometimes after his death. I haven't seen this bug playing alone, but it can be because I don't use a bow. Bug was visible to both of us and even after death it was visible.
