1.

Idle zombies can indeed do this, but it's not because they're idle, its mainly because of lag (crappy ROBLOX servers [giff 64 tick]) and hitboxes. Idle zombies can usually outspeed humans (even when running), so even though on YOUR screen it looks like they're behind you, in reality, they're on your ass and hurting you (serverside, they're on your ass, clientside, they're behind you).

2.

Annoying, but you can just shoot them as they move predictably.

3.

They move predictably.

4.

Basically what every other smart zombie would do anyway - in fact, I think idles target less than actual players. Idles go RANDOMLY, they do not have a specific person they lock onto, I'm pretty sure it's just the closest person to where they spawn. Real players, however, will almost always target low HP players.

TL;DR

ROBLOX servers suck, git gud.
