CSS for toggle bottons in IE8

The toggle bottons are not corectly displayed in IE8. I suggest the following addition to the module_filter_tab.css :

.toggle-enable div:before {
  left: -22px\9;
}
.toggle-enable div:after {
  right: -28px\9;
}
.toggle-enable.enabled {
  filter : progid:DXImageTransform.Microsoft.gradient(startColorstr='#DEDEDE', endColorstr='green');
}
.toggle-enable.enabled.disabled, .toggle-enable.off.disabled  {
  filter : progid:DXImageTransform.Microsoft.gradient(startColorstr='#DEDEDE', endColorstr='orange');
}  
.toggle-enable.off {
  filter : progid:DXImageTransform.Microsoft.gradient(startColorstr='#DEDEDE', endColorstr='red');
}
