fast/workers/worker-document-leak.html introduced in https://trac.webkit.org/changeset/138693,
but fails on Qt with the following diff:
@@ -1,4 +1,4 @@
Verify that creation of a worker does not leak its creating document.
-PASS: did not leak documents during test run
+FAIL: leaked documents during test run (started with 1, ended with 3)
I skipped it to paint the bots green: r138710. Please unskip it with the proper fix.
I don't know how to build the Qt port on any platform, so unfortunately can't help debug what's going on. You could try adding more calls to gc() at the end of the test, to try to force collection of the objects associated with the worker and the iframe's DOM.
