Will a FortiAP eventually "give up" on trying to form a wireless bridge?

Let's say that a Ethernet-connected FAP is setup to form a wireless Ethernet bridge with another FAP.

Now if the two radios go out of range each other, then a week later go back into range of each other, will the bridge connection still automatically reconnect? Or will one or both the APs have given up trying to reach the other?

Is there some kind of timer that determines this behavior?
