Pig and Happy Ghast Dsync Glitch

When you have a pig in a boat attached to a happy ghast and you ride it and hold a carrot on a stick you sink down to the ground but the happy ghast acts as if you are where you were when you held the carrot on a stick. (I’m assuming this applies to stiders too.) Also if this has already been report then the search function in Mojira needs to be fixed also because every time I try to search it nothing comes up but the it gets flagged as duplicate.
