This test used to work fine in nwsapi 2.2.0:

<table>
    <tbody>
                       <tr id="tr1">
                                <td>1</td>
                        </tr>
                        <tr id="tr2">
                                <td>2</td>
                        </tr>
                        <tr id="tr3">
                                <td>3</td>
                        </tr>
                        <tr id="tr4">
                                <td>4</td>
                        </tr>
                        <tr id="tr5">
                                <td>5</td>
                        </tr>
                        <tr id="tr6">
                                <td>6</td>
                        </tr>
                        <tr id="tr7">
                                <td>7</td>
                        </tr>
    </tbody>
</table>
mywrapper.querySelectorAll('table tr:nth-child(even)');

This query should return 3 elements: tr2, tr4 & tr6. And it did in version 2.2.0 But in the latest version (2.2.7) it returns no matches.

The same goes for :nth-child(odd)

@skerit can you please send a minimal but complete failing test case and specify your browser / environment ? The HTML fragment you sent seems to be working for me in a standard browser environment.
