Custom base64 image cursor with Opera - possible?

问题

I have the following Javascript:

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

And it works with Google Chrome, but not with Opera. Any known reason or workaround possible?

Same style for background image works in Opera just fine >>

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

Opera does not support urls for cursors, see http://www.quirksmode.org/css/cursor.html.
