I have a typical link on a page. On hover, the link receives a border color and border-radius. In Safari 6, I am noticing that when the mouse leaves the link there is a very faint border color left behind. If you hover again over the link, the border gets darker and darker in some cases, even though the border-color is not set. If border-radius is not set, the issue does not occur.
I cannot repeat the issue in Firefox or Chrome (for Mac). The simplest fix I found was to specify a solid or transparent border color for the base anchor style. Could this just be a Safari rendering bug?
