Looks like it's failing on GTK as well: http://test-results.appspot.com/dashboards/flakiness_dashboard.html#group=%40ToT%20-%20webkit.org&tests=css3%2Fflexbox%2Fcontent-height-with-scrollbars.html.
Looks like a rounding error. I would guess that this works in Chromium because we have sub-pixel layout enabled. Although, that doesn't explain why it's not failing for Qt/Efl.

Maybe Qt and Efl have scrollbars that are an even number of pixels, allowing the rounding to work?
I'll see if I can change the test so it'll work on all platforms.
