wpa_supplicant sending Response Identity twice

I am connecting with wpa_supplicant to hostapd over a wired connection.
Wireshark shows that wpa_supplicant sends out two EAP packets (Response
Identity). The first one w/o and the second one w/ the identity
information provided in the network section of wpa_supplicant.conf

hostapd takes the first packet for generating the RADIUS request. The
identity information from the second packet won't be used, and thus the
authentication fails.

Is it intended behavior of wpa_supplicant to send out two separate
Response Identity packets? Or is there any setting for controlling this
behavior (maybe on hostapd side)?

I tested the effect of eapol_version=2 in wpa_supplicant.conf: The
version of the second packet is changed, but the first packet w/o
identity information is still sent as before.

Note: I tested with versions 0.6.10 and 0.7.3 because I'm tied to an old
