Make block-styled links work in old IE

For when you have a link in your page styled as a block element, and the area of the link is not clickable in IE. Turns out adding a transparent background somehow makes it clickable.

.lte9 & {
    /* Hack because IE doesn't show link as clickable */
    background: url('data:image/gif;base64,R0lGODlhAQABAPAAAP///wAAACH5BAEAAAAALAAAAAABAAEAAAICRAEAOw==');
}

A sure telltale sign of this as an issue is if you add a border to the link it shows up, and you can click the border but not the insides. No idea why this happens, probably because IE.
