+ * Test that event listeners are properly fetched even if one of the listeners
+ * don't have a Debugger.Source object (bug 942899).
+ *
+ * This test is skipped on debug and e10s builds for following reasons:
+ *  - debug: requiring sdk/tabs causes memory leaks when new windows are opened
+ *    in tests executed after this one. Bug 1142597.
+ *  - e10s: tab.attach is not e10s safe and only works when add-on compatibility
+ *    shims are in place. Bug 1146603.
