Actionscript 3 :: Setting Cursor Priority With AIR Native Cursors

Is there a way to set the priority (CursorManagerPriority.HIGH) of a mouse cursor set via Mouse.cursor = '...';?

Long story short, I've had to resort to using the CursorManager to apply cursors, because setting the priority is crucial for my application due to the HTML control overriding all cursor changes without a high priority. Setting cursors with the cursor manager totally works, but the cursors aren't as fast/response as those rendered at the OS level (as described here).

If there isn't a way, my next question is: is there any way to suppress the cursor changes made by the HTML control? Setting mouseEnabled = false does it... but disables all mouse events on the HTML page, so that doesn't work.

This doesn't work:

setInterval(function():void { Mouse.cursor = 'ibeam'; }, 100);
Setting a cursor with a high priority works, however:
// ibeamCursor is an embedded PNG
CursorManager.setCursor(ibeamCursor, CursorManagerPriority.HIGH, -2, -4);

(this code is used at mx:Application scope)
