yosin@ / kochi@ may have more knowledge, but I don't think you should remove
this DCHECK. Could you first pinpoint which one is broken?
If it's GetDocument().NeedsLayoutTreeUpdateForNode() that is returning false,
then probably you need to call GetDocument().UpdateStyleAndLayoutTree()
somewhere.

Done.

   return isConnected() && SupportsFocus() && !IsInert() &&
          LayoutObjectIsFocusable();
 }
