Ah yes, but top thing is just a listing of the protocol variations Chrome
supports.

I used "50.0.2661.94 (64-bit)" for Linux and it then shows lots of other sites
doing h2 in the table below, but not ssllabs.com - suggesting that ssllabs.com
doesn't do h2. I also tried the devtools network tab and checked, but didn't
see any h2 there either.

I also run the "HTTP/2 and SPDY Indicator" plugins in both browsers and
neither of those plugins show the h2 symbol for ssllabs.com...
