/teleport ... facing ... is not working correctly

The new /teleport ... facing is not working correctly
for example:

 
/teleport @s ~ ~ ~ facing 0 0 0 

would not rotate the player at all

and use facing entity would have incorrect results too,for example

 
/teleport @p ~ ~ ~ facing entity @e[type=armor_stand,limit=1] feet 

and

 
/teleport @p ~ ~ ~ facing entity @e[type=armor_stand,limit=1] eyes 

both command produces unintended result
