Would you be able to share a sniffer capture showing such a case? This
seemed to be needed when the forwarded packet was shorter than minimum
Ethernet frame (even if not really going out on Ethernet which is the
somewhat strange part here and likely specific to some APs), but I'm not
sure in which cases the other frames would be short enough to trigger
this issue.

Furthermore, these are not really supposed to be "extra erroneous IEs",
but some arbitrary padding at the end of the "Ethernet" frame.
