      Description

      https://tools.ietf.org/html/rfc7540#section-6.9.1

      A sender MUST NOT allow a flow-control window to exceed 2^31-1
      octets. If a sender receives a WINDOW_UPDATE that causes a flow-
      control window to exceed this maximum, it MUST terminate either the
      stream or the connection, as appropriate. For streams, the sender
      sends a RST_STREAM with an error code of FLOW_CONTROL_ERROR; for the
      connection, a GOAWAY frame with an error code of FLOW_CONTROL_ERROR
      is sent.

      Currently, TS accepts such a invalid flow control.

      It would cause overflow but is not critical, so I'm setting issue type as Improvement.
