Q: Why do we need to call |hasSelection|?
It seems just call |FrameSelection::collapseToEnd()| is enough.
|WebLocalFrameImpl::setelectionRange()| is one line function, it just call
|FrameSelection::toNormalizedRange()|.

Done.

+        return false;
+
+    // Collapse the selection to end of Range Selection.
+    FrameSelection& selection = frame()->selection();
+    return selection.collapseToEnd();
