I don't think I've seen anything but a browser ever do this, fixing an incomplete chain. curl, wget, several different programming languages, everything just fails to verify.
I can understand why it wouldn't be supported, but you also see why users and developers experience this as just "SSL/TLS just gives you these weird errors sometimes" and pass around solutions to turn off verification.
