I would suggest a new keyword 'group-box'. If that keyword is used, the union of border boxes of the current element and all descendant elements get computed and used to specify the clipping area.

That's still going to clip off box-shadows and outlines etc.

Why not simply allow 'mask-clip:none'?
Not sure if that can be easily implemented on all platforms (since some graphics libraries and some HW accelerated need a maximum size anyway).

But my main concern are percentage values that always need to be resolved to to one of the boxes on mask-clip. Sometimes you want them to be relative to the whole group.

For your shadow example we have filter-box.
