The thought occurred to me that the res= from the extension spawn
was ending up being returned from the bridge.

"Thou shalt not poison the return value". Made the change
and it appears to allow blind xfers to work as normal.

If I'm wrong, reopen the bugs. But it looks good to me!

Many thanks to putnopvut for helping me reproduce this!
