Change looks good to me, but could you explain the extra complexity in ChangeRegionOversetTask? That matches existing behavior, but seems unnecessary.

> Source/WebCore/inspector/InspectorCSSAgent.cpp:310
> +: m_cssAgent(cssAgent)
> +, m_timer(this, &ChangeRegionOversetTask::onTimer)

Style: These lines should be indented.

> Source/WebCore/inspector/InspectorCSSAgent.cpp:352

Why the extra copy to a vector first? Under what circumstances would m_namedFlow be non-empty at the end?

Could this be simplified to just the following, or is there something I'm missing:

    for (HashMap<WebKitNamedFlow*, int>::iterator it = m_namedFlows.begin(), end = m_namedFlows.end(); it != end; ++it)
        m_cssAgent->regionOversetChanged(it->key, it->value);
    m_namedFlows.clear();

I see you are copying the style of UpdateRegionLayoutTest, but I'd have the same question for that.
