URGENT Fix on Bedrock Wither Behavior

It is easily one of the worst things about the game, for Bedrock edition players, that the number one threat of the Wither boss is LAG. Specifically, there is a major issue in which the Wither will use its dash action immediately after dropping to half health, except it goes DOWN, breaking absurd amounts of blocks that cause so much lag that even in minimal settings it can be unbareable. That, and the fact that the Wither will then use its dash action underground, breaking even more blocks. It is such that the frame lag often prevents players from escaping the fight, even with great preparations like enchanted apples and totems. The dashing action by itself on the surface can be bad enough already. This has to stop. Thousands of skilled players avoid the Wither simply because they do not have the hardware to fight it. At the very least, WHILE this is not fixed, please do NOT fix any Wither "cheesing" strategies, as this will completely eliminate the possibility of getting beacons for many of us.
