No AP mode operation with ap_scan=1 if no matching network is found

i have an issue with AP scanning and selection. After power-up the
device should scan for a known ssid and if it does not find it,
initialize an new network in AP mode operation. This is well the
behaviour as described for the 'ap_scan=1' config option.
This is my corresponding wpa_supplicant.conf:
If the access point with the ssid "HOME_NETWORK" is not found, the
device should go into AP mode operation, as far as I understand the
'ap_scan=1' config option. Unfortunately, it does not.
Running wpa_supplicant in debug mode I can see that the supplicant
scans for the ssid "HOME_NETWORK" three times and always ends up with
"No suitable network found". However, instead of starting to operate in
AP mode, the supplicant initiates a sched_scan:
No suitable network found
Beginning of SSID list
Add wildcard SSID to sched_scan
add to filter ssid: HOME_NETWORK
Starting sched scan: interval 10 (no timeout)
Did I miss something?
