They have the same hostap (hostapd + wpa_s) version:
Hostapd v2.10-devel-hostap_2_9-102-g12de14907+
wpa_supplicant v2.10-devel-hostap_2_9-102-g12de14907+

I've tested with v2.8-devel-hostap_2_7-313-g3e949655c+ too.

In this short video (https://www.youtube.com/watch?v=f6rrHIGpePA -
running on VirtualBox) you can see the problem in action. Through this
video you can see that it works with 4.16 and 4.17, and doesn't work
with 4.19 (I forgot to repeat the test with 4.18, but I confirm that
it has the same behaviour as 4.19).
