>+
>+        Refactor hasMarkedTextWithCompletionHandler to use Editor::hasComposition, instead of computing the actual
>+        marked text range. The latter is more expensive and unnecessary, since it uses TextIterator from the document
>+        root to find editing offsets. This makes the cost of determining whether there is marked text proportional to
>+        the document size.
>+
>+        This matches behavior in legacy WebKit, as well as iOS.
