So far I can say that with scan_ssid=1 after rebooting the AP the connection is properly re-established. Looks promising.
Your results make sense. The driver is fairly passive in all this. It gets TX requests from the MAC layer, and passes received data back up to that layer. It seems likely that the MAC layer built into r8712u is not keeping track of missing responses, or it is not probing the AP. In either case, it would not be productive to devote any effort to fixing that part when either using NetworkManager or setting scan_ssid for wpa_supplicant establishes periodic scans. When these fail to get response from the AP, the softmac code will respond, as you see.
The ultimate fix will be to convert to the driver to use mac80211, which is a much better MAC layer. That is on my TODO list, but it has low priority.
