Scoreboard teams leave doesn't work if first player fails

If you have

/scoreboard teams leave @e[tag=test] @e[tag=test0]

and there's no entity with the tag "test" the entity with the tag "test0" will not leave the team.

This only happens if the first player is a selector without result entity, if it happens to the second one, the 3rd, 4th, 5th, etc. will still leave the team, if the first is not a selector the rest also succeeds.
