Minecraft Regonizes Boats And Minecarts As Horses

[(Note) Top Its Survival AND Creative] So Whenever I Go Into A Minecart Or Boat (On Any Computer I Tried It On My Friend's) It Recognizes The Boat/ Mine Cart As A Horse Because When I Get Into It What Happens is The Message That Appears is "Type LShift To Dismount" That's Basically The Bug It Doesn't Allow You To Right Click To Get Out It Makes You LShift And Comes Out With The Message.
