jQuery >=3.4.0 uses a special focus/blur handler pair needed to fix various issues with checkboxes/radio buttons as well as being able to pass data in focus triggers. This leaves extra focus & blur events if any of these events were ever listened to at a particular element. We've started skipping these handlers in the `domEqual` assertion in jquerygh-1930 but we missed a case where an event is triggered before any handler is attached - jQuery >=3.4.0 attaches then an extra noop listener just to force the code path to go through the setup code before the trigger happens. We now skip this extra handler as well. This fixes a test failure in "dialog: methods" destroy tests. Ref jquery/jquery#4496 Ref jquerygh-1930
