Subject: [PATCH] Fix off tickregion sync teleport
Folis's teleportAsync implementation has some checks missing during the sync teleportation checks, if we are teleport to the edge of the tickregion, it is still asserting that we are in the same tickregion and moved us directly, but there is actually some logics is already touching the stuff out of current tickregion.So we added some new edge checks to the sync teleportation checks which will check the tickregion belonging in a shape of cycle which is in min(entity's bounding box + simulate distance, 6) of radius to fix that issue
