Child/grandchild component props should persist across parent state changes

For example: I use a Card with a native slot (or the component swap method, either way). I place an instance of my custom component in that slot. I change a text property in my custom nested component. Then I go up to the parent layer and change the state of the Card (assuming it’s interactive). The text prop I set on my nested, sub-component does not persist across states. Currently, it does not!
