Steps to reproduce the problem:
1. Go to https://dev.ssllabs.com/ssltest/viewMyClient.html
2. Scroll down to see the Cipher Suites Section
3. There is TLS_RSA_WITH_3DES_EDE_CBC_SHA (0xa)

What is the expected behavior?
This cipher should not be there.

What went wrong?
https://sweet32.info/
3DES is weak and slow, and can be weaker as the time goes. 
However, some servers are strangely configured to prioritize 3DES over AES, make Chrome negotiates 3DES with those servers. 

Did this work before? No

Treat 3DES the same way as RC4.
Remove DHE from the fallback cipher list and add 3DES. 
Also, in order to prevent future attacks with ciphers with 128-bit block sizes, please limit the data that is encrypted by the same key.
