[Common UI] CommonActivatableWidgetSwitcher layout issues?

There is a Vertical Box wrapping CommonActivatableWidgetSwitcher that limits the size。Everything works fine in the Content Examples.

But if there is no wrapping box that limits the size of the widget, its size is determined by the very bottom position of the inner widget, even if the inner widget is full-screen. This causes some widgets such as expecting adaptive zoom to always be at the bottom of the viewport to display wrong.



Is this a bug? Or is there another workaround to make the content display correctly?
