This appears to have regressed with: r220278
Comment 2 Joseph Pecoraro 2017-08-28 14:03:41 PDT
-    if (!ScriptGlobalObject::get(state, "InspectorFrontendAPI", frontendApiObject)) {
+    auto value = state.lexicalGlobalObject()->get(&state, JSC::Identifier::fromString(&state.vm(), "InspectorFrontendHost"));

InspectorFrontendAPI turned into InspectorFrontendHost!
Comment 3 Joseph Pecoraro 2017-08-28 16:09:30 PDT
I spent a bunch of time seeing what it would take to write a test for this. In general it seems we lack tests for selecting context menu items.

There are some LayoutTests to show a ContextMenu that use `eventSender.contextClick`. There are no LayoutTests to select an item in the ContextMenu, which seems okay given there might be platform differences there.

In this case the Web Inspector page, not the inspected test page, is what is triggering context menus. It doesn't have `eventSender`, `internals`, etc. We can show a ContextMenu with `InspectorFrontendHost.showContextMenu`, but selecting an item is not immediately possible. My best idea would be to introduce `InspectorFrontendHost.testContextMenuSelectItemAtIndex` but I don't like that. It adds surface area to an object we want try to keep as small as possible since its APIs extend the power of the Inspector frontend page.
