Cannot find _button("foo", _in(_div("bar"))) with more than 3 nesting levels

For example, the DOM tree looks like this:

<div class="x-panel-mc-bwrap" id="ext-gen12">
  <div class="x-panel-mc-footer x-panel-mc-footer-noborder" id="ext-gen14">
    <div class="x-panel-btns-ct" id="ext-gen518" style="">
      <div class="x-panel-btns x-panel-btns-center" style="" id="ext-gen889">
        <table cellspacing="0"><tbody><tr>
          <td class="x-panel-btn-td" id="ext-gen15">
            <table border="0" cellpadding="0" cellspacing="0" class="x-btn-wrap x-btn x-btn-text-icon " id="ext-comp-1053" style="width: auto;"><tbody><tr>
              <td class="x-btn-left"><i>&nbsp;</i></td>
              <td class="x-btn-center" id="ext-gen520" style=""><em unselectable="on">
                <button class="x-btn-text" type="button" id="ext-gen17" style="background-image: url(http://my-domain.com/path/to/image/search.png);">Search</button>
              </em></td>
              <td class="x-btn-right" id="ext-gen550"><i>&nbsp;</i></td>
            </tr></tbody></table>
          </td>
          <td class="x-panel-btn-td" id="ext-gen23">
            <table border="0" cellpadding="0" cellspacing="0" class="x-btn-wrap x-btn x-btn-normal " id="ext-comp-1054" style="width: auto;"><tbody><tr>
              <td class="x-btn-left" id="ext-gen547"><i>&nbsp;</i></td>
              <td class="x-btn-center" id="ext-gen535"><em unselectable="on"><button class="x-btn-text" type="button" id="ext-gen25">Reset</button></em></td>
              <td class="x-btn-right"><i>&nbsp;</i></td>
            </tr></tbody></table>
          </td>
        </tr></tbody></table>
      <div class="x-clear"></div>
      </div>
    </div>
  </div>
</div>

Sahi can find the Search button when using:

_button("Search", _in(_div("ext-gen14")))

But it cannot find it when using:

_button("Search", _in(_div("ext-gen12")))

And it can find it again when using:

_button(0, _in(_cell("Search", _in(_div("ext-gen12")))))

Any body knows why does it happen? Is there any limitation of nesting levels in finding buttons inside some other elements (while not in finding cells)? Thanks a lot.

PS: I'm using the latest version of Sahi, the browser is IE8 on Windows 7, and my SUT is built with ExtJS 2.0.2.
