I can still run while i'm right clicking a bow, sneaking, crouching, right clicking a shield, right clicking a crossbow, right clicking a trident. If i tap sneak button while i'm running, i can run while sneaking. And i can see block particles under my feet. But when i stop running, i can't run again while i'm sneaking.
