r277493 removed the test from the general TestExpectations. The test was marked as [ Pass Failure ] without bug associated. r277493 implements correct behavior for https://www.w3.org/TR/resource-timing-1/#dom-performanceresourcetiming-secureconnectionstart (when a TLS connection is re-used, the secureConnectionStart should be the same as fetchStart) for Cocoa based ports. We would need a similar implementation for GLIB based ports.
