curl: Proxy CONNECT response poisoning via authentication retry in cf-h1-proxy.c (libcurl)

Summary: When an HTTP/1.x proxy returns a 407 with no Content-Length and no chunked transfer-encoding, lib/cf-h1-proxy.c singleheader sets ts-keepon = KEEPONDONE but never sets ts-closeconnection = TRUE. Because ts-closeconnection and conn-bits.close both stay false, the CONNECT tunnel state...
