Consider a view with subcanvas A which has a subcanvas B which as a component C.
The problem is that the effectivelyVisible of the widget wrapper of subcanvas B prevents the widgetState from
being updated.
Begin with everything visible.
Set subcanvas A to not visible. effectivelyVisible = nil
Ask for visiblity of component C, i.e. change its state. effectivelyVisible = false
Set subcanvas B to not visible. effectivelyVisible being false prevents updating of widgetState.
Set subcanvas A to visible.
Result: subcanvas B is still visible.
Recommened fix is to change WidgetWrapper>>forceVisibility: to;
forceVisibility: aBoolean
widgetState isVisible: aBoolean.
effectivelyVisible == aBoolean ifFalse:
[effectivelyVisible := nil.
self invalidate].
