I noticed a strangeness in the TLS 1.2 Handshake and I don't know if I'm missing something.
As you can see in this screenshot, the browser (Chrome) puts the value 0x0301 as version in the Record Layer but it puts the 0x0303 value as version in the Handshake record. The used version is TLS 1.2 (SSL 3.3) actually. If I got it right, even the RFC5246 says that the value is 0x0303 for this version. So, Why the browser puts 0x0301 in the Record Layer?
