About the pull request

Buckled mobs didn't have their TRAIT_IMMOBILIZED removed properly since we return early from launch_towards() if buckled

cmss13/code/modules/mob/living/living.dm

Lines 401 to 405 in 939e283

	/mob/living/launch_towards(datum/launch_metadata/LM)
	if(src)
	SEND_SIGNAL(src, COMSIG_MOB_MOVE_OR_LOOK, TRUE, dir, dir)
	if(!istype(LM) || !LM.target || !src || buckled)
	return

Therefore any callbacks in end_throw_callbacks are never invoked. In the case of xeno throws we rely on end_throw_callbacks to remove our immobilised trait

Fixes #5420

Explain why it's good for the game
