Code completion popup obscures code

Is there any way to force the code completion popup to always drop downward? I find I’m often working near the bottom of the editor window. However, when you’re closer to the bottom of the editor window than the height of the CC popup, it displays above rather than below the current insertion point. This completely obscures the code immediately above, which is normally the code I’m working on and need to see. I’m guessing this is because the CC popup is clipped to the editor window boundary. But could it be reworked so it could drop down over the console pane so it could be forced to drop down always?
