Hmm, I can see why it happens, but there is no quick fix for it. The definitions are stored in the text next to the acronym and then hidden by CSS. When you hover over the acronym, the CSS is changed to show the popup. I'll see what I can do, but to be honest, I think this could even be considered a browser bug - if an element is hidden they should not consider it as marked.
