-PASS: the anchor for 'www.foo.com' has been created.
+Failed: the expected content was 'The <a href="http://www.foo.com">www.foo.com</a> should be underlined and there is an anchor node created for it.', but the actual result was 'The www.foo.com should be underlined and there is an anchor node created for it.'.

Assuming the test is failing because we're hitting the reentrancy guard added by r167818, we should probably break runTest() in the layout test into multiple pieces (using setTimeout() calls).

Yep, that fixes the test.

Correction, I must not have been running against the build of WebKit I thought I was.

Incorrect fix: use setTimeout() in test

Perhaps the re-entrant behavior needs to be fixed in WebCore itself.

The better way to write this is:

    for (auto& run : runs) {
