I think this was a mis-paste -- we do fail the test linked here, but just for reasons of fuzziness/imprecision; to a first approximation, we render the testcase the same as Chrome does, and the same that we render the reference case.) The actual relevant test for this behavior (which includes the "half slice of a blue-diamond" quote from comment 8) is this one: https://wpt.fyi/results/css/css-backgrounds/css3-border-image-repeat-repeat.html ...which is also tracked in bug 1820659.
