Drag box inside inline block

I don't know if this bug fixed after fixing this bug https://bugs.webkit.org/show_bug.cgi?id=79417
I have both bugs in my cromium (18.0.1025.168 (Developer Build 134367 Linux) Ubuntu 12.04) now.

If draggable element inside inline-block then it invisible or white.
if you add the declarations width: 100% and height: 100% to body, html, the box will invisible.
if not, the box will fully white.

To see the error, you should uncomment class a. Then you can comment width, heigth declarations to see another kind of bug.

Safari Drag 'n Drop Bug Example

.SlidingPuzzleFigure {
    /** This causes safari to make the dragged clone invisible. */
  display: inline-block;
}

li:active { 
  /** Safari needs this, else the dragged clone is invisible. 
  /* Uncomment to see the fix. */
  /* opacity: 0.999; */
}

Blink and WebKit do not allow dragging in the "Safari Drag 'n Drop Bug Example', but Gecko does.

Gecko does not allow the box to be dragged in the first test case, but Blink and WebKit do.

I'm not sure which behavior is correct.
