No, wpa_supplicant shouldn't have to do that, mac80211 should do that
automatically once a new BSSID comes in. The problem seems to be between
mac80211 and your AP in that mac80211 associates to another AP and then
tries the target one but the target one doesn't like that so we should
at least try to disassociate from the previous one first.

mac80211 should be responsible.

I tend to think that is rather questionable behaviour, how can the
second AP know that you're still in range to the first and can even
disassociate from that one?
