I have a OO.ui.PopupWidget that can be fairly long (depends on the content, which loads asynchronously).
I have autoFlip on, but it has to be really close to the bottom to flip (since the popup is almost empty at the start), and when it fills later, it doesn't re-flip.
Is there a way to either "reserve" space, so it will pre-emptively flip so that it would have at least "y" pixels, or is there a way to force it to flip if it gets too large?
