<span class="quote">&gt; Source/WebCore/page/animation/KeyframeAnimation.cpp:369
&gt; +    auto* styleScope = Style::Scope::forOrdinal(element, m_animation-&gt;name().scopeOrdinal);
&gt; +    if (styleScope)
&gt; +        styleScope-&gt;resolver().keyframeStylesForAnimation(*m_object-&gt;element(), m_unanimatedStyle.get(), m_keyframes);</span >

Could define the variable inside the if.

<span class="quote">&gt; Source/WebCore/platform/animation/Animation.cpp:167
&gt; -const String&amp; Animation::initialName()
&gt; +Style::ScopedName Animation::initialName()
&gt;  {
&gt;      static NeverDestroyed&lt;String&gt; initialValue(ASCIILiteral(&quot;none&quot;));
&gt; -    return initialValue;
&gt; +    return { initialValue.get(), Style::ScopeOrdinal::Element };
&gt;  }</span >

Could just have this return const Style::ScopedName&amp; instead and have the global be a NeverDestroyed&lt;Style::ScopedName&gt;; would be slightly more efficient.</pre>
