nested handlers are not resolved

[o0101]

e.g.

       F` <p>
          <button type=submit class=ok title=Acknowledge value=ok>OK</button>
          ${otherButton ?
            F`<button title="${otherButton.title}" click=${otherButton.onclick}>${otherButton.title}</button>`
            :
            F`<!-- other button -->`
          }
        </p>`

The otherButton.onclick click handler is never found by our system, and remains unusable.
