But you would need to override all these calls (or remove the layout bead from
CSS)
addBead(new (ValuesManager.valuesImpl.getValue(this,
"iBeadLayout")) as IBead);
You wouldn’t need to if the wrapper was in itself an IBeadLayout, but then it
would have to remove itself before adding its wrapped bead.
To me it seems the main mode of communication between beads should be
notifications. Another thing that might work here is to create a
CheckForVisibleBeforeLayoutBead which would be added before the layout bead. It
would listen on ‘layoutNeeded’ and stopImmediatePropagation() unless the host
is visible.

I was thinking the wrapper would just wait for the show event then set the
strand on the actual layout bead. I'm not sure how much actually would
need to be proxied or forwarded in that case. Or maybe the wrapper could
just put the actual layout bead on the strand.
Just tossing ideas around...
