r=me, nice work!

What's the difference between .isProcessingUserGresture() here and .userIsInteracting() above?

> Source/JavaScriptCore/debugger/Debugger.cpp:618
> +    JSObject* scopeExtensionObject = m_client ? m_client->debuggerScopeExtensionObject(*this, globalObject, debuggerCallFrame) : nullptr;

Nice.

> Source/WebCore/inspector/agents/page/PageDebuggerAgent.cpp:126
> +        m_breakpointActionUserGestureEmulationScopeStack.append(makeUniqueRef<UserGestureEmulationScope>(m_inspectedPage, true));

What a mouthful. I like the stack idea though.

> +            emulateUserGestureLabel.appendChild(document.createTextNode(WI.UIString("Emulate User Gesture")));

Please add a location to the UIString (@ Evaluate JavaScript breakpoint action menu in Sources tab)

> Source/WebInspectorUI/UserInterface/Views/LogContentView.js:84
> +            this._emulateUserGestureNavigationItem = new WI.CheckboxNavigationItem("emulate-in-user-gesture", WI.UIString("Emulate User Gesture"), WI.settings.emulateInUserGesture.value);

Please add a location to the UIString (@ Option in Console Tab)

Please (create a task to) add this to the documentation as well. =)

`isProcessingUserGesture` is a WebCore concept whereas `userIsInteracting` is a WebKit (WebProcess) concept.  I believe the latter is necessary (in addition to the former) for more "native" interactions like showing the iOS keyboard when evaluating `input.click()` (see Bug 197269).
