Member signature parameter span contains closing but not opening parens

In the HTML generated for a member signature for an executable element, the opening parens is outside the "parameters" (previously "arguments") span, but the closing parens is inside the span.

<div class="member-signature">
  <span class="modifiers">public</span>
  &nbsp;
  <span class="return-type">int</span>
  &nbsp;
  <span class="member-name">m</span>
  &#8203;(
  <span class="parameters">int&nbsp;arg)</span>
</div>

It would be better if both were inside the span or both were outside it.
