[Sb] requestLayout when visibility state changes

There seems to be some nondeterministic interaction between the mobile
icon's `isVisible` and `visibilityState` flows. We are already
requesting layout when `isVisible` changes, but visibilityState can also
need the layout changes if the icon changes between hidden, dot, or
normal visibility states.

This should address the issue where during initial layouts the icon can
be misplaced until another change in the icon container triggers a
layout pass.
