It's containment, not isolation. There are many things from outside the layout contained element that can influence what's inside it. It's the other way around that we're trying to block.

There may be merit to bidirectional isolation as well, and I think we've already run into a few situations where interesting optimization would be enabled by having it, but to get there there are many more holes than this one to plug, and it's not completely clear it's even doable.

I think looking into whether full isolation would be practical is reasonable, but the fact that containment as currently defined doesn't do it is not a bug.
