+// Because link-coloring for visited links is asynchronous, running
+// reftests that involve link coloring requires that we poll for the
+// correct result until all links are styled correctly.

+// A requirement of these reftests is that the reference rendering is
+// styled correctly when loaded. We only poll for the tests.
+
+var gTests = [
+ // there's also an implicit "load visited-page.html" at the start,
+ // thanks to the code below.
+
+ // IMPORTANT NOTE: For these tests, the test and reference are not
+ // snapshotted in the same way. The REFERENCE (second file) is
+ // assumed to be complete when loaded, but we poll for visited link
+ // coloring on the TEST (first file) until the test passes.
