data-hide="always" on expand quickly hiding again.

[noahmatisoff]

I'm using jQuery datatables as well as this repository, and have the snippet below in my table's head:

<th data-class="expand">Col 1</th>
<th>Col 2</th>
<th data-hide="always">Col 3</th>
<th data-hide="phone">Col 4</th>
<th data-hide="always">Col 5</th>
<th data-hide="always">Col 6</th>
<th data-hide="always">Col 7</th>
<th data-hide="always">Col 8</th>
<th data-hide="always">Col 9</th>

In the snippet above when using the "always" option, when showing the hidden data is quickly re-hides the data. This means that the data is hidden and the row shows the "-" icon indicating it's shown although it then hides it a few hundred ms later.

What is this bug?
