Nice.

> Source/WebCore/inspector/InspectorFrontendHost.cpp:164
> +    auto& globalObject = *m_frontendPage->mainFrame().script().globalObject(world);

In the old code, m_frontendPage can be nullptr.

How about using `HashMap::removeIf`?

Remove space between [&] and (Frame& frame).

> Source/WebCore/inspector/agents/InspectorTimelineAgent.cpp:297
>  void InspectorTimelineAgent::startFromConsole(JSC::JSGlobalObject* exec, const String& title)

Let's rename exec to `globalObject` or `lexicalGlobalObject`.

> Source/WebCore/inspector/agents/page/PageRuntimeAgent.cpp:136
> +    m_inspectedPage.forEachFrame([&] (Frame& frame) {

Remove space between [] part and () part in lambda.
