Unexpected error raised for table marked as presentation

Issue Description

The following code snippet was flagged as a serious error with axe for use of the headers attribute.

<table role=presentation>
 <tr><th hidden>...</th><th>...</th></tr>
  <tr>
     <td headers=foo hidden>...</td>
     <td>...</td>
  </tr>
</table>

However, this doesn't make any sense to flag as an error because:

1. the table has been marked as role=presentation so table semantics are kicked to the curb anyway.
2. the cell with the erroneous headers attribute on it also has the hidden attribute, so even if the table was still exposed as a table, the cell is hidden so still can't be an accessibility issue.

Thanks for the report @scottaohara. I agree with you, tables with role=presentation shouldn't match the td-headers-attr rule.

Valdiated with the latest axe-core develop branch code base,
in the test script table has been marked as role=presentation and td atrribute as hidden so test snippet should not fail for td-headers-attr rule

<table role=presentation>
 <tr><th hidden>...</th><th>...</th></tr>
  <tr>
     <td headers=foo hidden>...</td>
     <td>...</td>
  </tr>
</table>
