Previously, wpa_supplicant did not terminate the remain-on-channel session, but rather waited until the requested comeback delay had expired, and then tried to send the GAS frame (potentially to save the time that is required to schedule a new remain on channel flow). This might cause unnecessary idle time (can be close to 1000 ms) in which the device might be off-channel. Ending the current remain-on-channel session and then rescheduling makes better usage of the time in this case. End remain-on-channel session due to receiving a delayed GAS comeback request from the AP.
