AsyncTree node loading icon repeats

[MD]

I noticed while expanding nodes in an AsyncTree that you can see the top 2px of the loading.gif repeat. Verified this occurrence in both IE and FF.

Figured it would be a quick fix and added a "no-repeat" to ~ln 43 in tree.css and ~ln 2030 in ext-all.css

.x-tree-node-loading .x-tree-node-icon{
background:transparent url(../images/default/tree/loading.gif) no-repeat !important;
}

However, after clearing cache and a hard refresh, it still shows the bg image repeating

Thanks. I have added in a few changes to the base icon css classes because they should all really be no-repeat.
