+ Fixed a test failure seen in web-timing-minimal-performance-now.html
+ https://bugs.webkit.org/show_bug.cgi?id=165542
+
+ Reviewed by Beth Dakin.
+
+ This test was always slightly wrong, but it is much more likely to fail
+ as of <https://trac.webkit.org/changeset/209462>.
+
+ * fast/dom/Window/web-timing-minimal-performance-now.html: < is not a
+ correct test for monotonicity. < tests for stricly increasing. <= is a
+ correct test for monotonicity. All computer clocks have some granularity,
+ so computer clocks are monotonic but not strictly increasing: you can
+ sample the clock twice in the same tick.
