使用Opera自定義base64圖像光標 - 可能嗎？

Question

我有以下的Javascript：

document.getElementById("test").style.cursor = 
    "url('data:image/png;base64," + 
    "iVBORw0KGgoAAAANSUhEUgAAABAAAAAQCAYAAAAf8/9hAAAAdUlEQVR42qW" + 
    "TSw7AIAhEZ8XCA3AFlt7/dG3SxEatQ1FIjGDg8Yu4HAHwHNeHBfSB7X0FQ+" + 
    "/EMjM9BXjvuYWI3kOOAAPMGx7bzFQNtta22Bpohkgl2AmigBNICjDMLdP/B" + 
    "xCB1Fr5Z2qiqhRgZv8AEaGAUspg3wU3VkqQQyYrAAAAAElFTkSuQmCC'), default"; 

而且它與谷歌瀏覽器工作，但不能與歌劇。任何已知的原因或解決辦法可能？

背景圖像相同風格的歌劇就好作品>>

document.body.style.backgroundImage = 
    "url('data:image/png;base64," + 
    "iVBORw0KGgoAAAANSUhEUgAAABAAAAAQCAYAAAAf8/9hAAAAdUlEQVR42qW" + 
    "TSw7AIAhEZ8XCA3AFlt7/dG3SxEatQ1FIjGDg8Yu4HAHwHNeHBfSB7X0FQ+" + 
    "/EMjM9BXjvuYWI3kOOAAPMGx7bzFQNtta22Bpohkgl2AmigBNICjDMLdP/B" + 
    "xCB1Fr5Z2qiqhRgZv8AEaGAUspg3wU3VkqQQyYrAAAAAElFTkSuQmCC')";

Opera不支持url S代表光標，看到http://www.quirksmode.org/css/cursor.html。
