gradient mixin vertical-three-colors on <tr> doesn't render correctly on IE11 or Edge

Created by: RodolpheGohard

Hi,

when applying a vertical-three-colors gradient on a <tr> in IE11, I get a buggy display: the gradient does'nt extend to the full width of the <tr>.

Here is a demo:

<style type="text/css">
   /* GENERATED FROM LESS .gradiented {
    .vertical-three-colors(#cccccc, #e9e9e9, 5%, #e9e9e9);
    }*/
    .gradiented {
        background-image: -webkit-linear-gradient(#cccccc, #e9e9e9 5%, #e9e9e9);
        background-image: -o-linear-gradient(#cccccc, #e9e9e9 5%, #e9e9e9);
        background-image: linear-gradient(#cccccc, #e9e9e9 5%, #e9e9e9);
        background-repeat: no-repeat;
        filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#ffcccccc', endColorstr='#ffe9e9e9', GradientType=0);
    }
</style> 

<table>
    <tr>
        <td>cell 1</td>
        <td>cell 2</td>
        <td>cell 3</td>
        <td>cell 4</td>
    </tr>
    <tr class="gradiented">
        <td>cell 1</td>
        <td>cell 2</td>
        <td>cell 3</td>
        <td>cell 4</td>
    </tr>
</table>

in this sample, running IE11, I only get the first cell to be filled. The situation doesn't happen if I remove the background-repeat: no-repeat; property, which makes me wonder why it's there to begin with.
