           Summary: Web Inspector: inspector/layers/layers-for-node.html
                    and  inspector/timeline/line-column.html are flaky

The two tests became very flaky after replacing Timer based queue with RunLoop one in https://trac.webkit.org/changeset/250655/webkit. The change seems to have revealed existing flaw in the tests as it essentially modified the timing of the event dispatches.
