Thanks for letting me know. I'll try to repro and will look if this is common behavior for all virtual drivers, or simply a bug in WireGuard that I need to address. If it is the latter, your patch below isn't quite correct; we'll probably address this instead by simply setting skb->protocol in xmit by peaking at the header, if skb->protocol is zero, and then keeping the rest of the logic the same elsewhere.
