Description

Expected Behavior

Port forwarding to work normally

Steps To Reproduce
  1. Connect to a remote using ssh
  2. Either manually port forward or use something that causes vscode to forward ports
  3. Wait for a reconnection (due to network interruption, or any other cause - i dont think it is relevant)
  4. When the remote connection is restored, forwarded ports no longer work correctly until the user removes and re-adds/forwards them. The connection to localhost on the user's machine will hang and not resolve until the ports are forwarded manually again
