method name should describe what it does, not where it is called from

could this logic should be added to the setStyle method?

+{
+    if (m_style->hasImage() || computedStyle->hasImage() || isImage() || isVideo())
+        setStyle(std::move(computedStyle));
+    else
+        setStyleInternal(std::move(computedStyle));
