Description

@deansheather

Trying to forward webtransport QUIC traffic from a QUIC server in a workspace to local doesn't seem to work. It may have something to do with MTUs and packet sizes.

It seems to be related to coder port-forward and not an issue with the QUIC server/client since using a different UDP forwarding method such as a vscode extension seems to work just fine (UDP encapsulated in TCP).
