This testcase wasn't accounting for the fact that "flex-wrap: wrap-reverse" flips the direction in which overflow is reachable/scrollable, in a flex container's cross axis (just as "flex-direction: column-reverse" does in the main axis). The CSSWG resolved on this here: https://lists.w3.org/Archives/Public/www-style/2014Sep/0187.html This commit makes the test account for this, by increasing the expected scrollHeight of the "wrap-reverse" pieces of the test (which have overflow that should be scrollable). Note that Chromium doesn't pass these amended subtests, because it doesn't correctly handle scrolling with wrap-reverse; this is covered by https://bugs.chromium.org/p/chromium/issues/detail?id=1114306 . (However, if I modify the test to use "wrap" instead of "wrap-reverse", then Chromium does pass these subtests. This indicates that Chromium does essentially agree on the expected value here, aside from that bug report about making the overflow scrollable.)
