WebSocket: error: 1002: Client MUST mask all frames (RFC-6455: Section 5.1)

Julia 1.3.1
HTTP.jl 0.8.8
MbedTLS.jl 0.7.0

Using a WebSocket.
This error gets logged when the connection is closed.
I looked into packet capture session and saw that the WebSocket close frame communication from the Julia side was missing a mask, as the error indicates. Seemingly harmless except for the log message makes me wonder what if anything is wrong.

Yep, the old code wasn't masking the CLOSE frame that was sent when a connection was closed. This has been fixed on HTTP#master.
