Impacted component(s)

Picker

Expected behavior

When an sp-picker is rendered with a given value that belongs to a (delayed) rendered slotted menu-item - the default label should display the value of the selected sp-menu-item.

Actual behavior

When a value is provided to sp-picker and the related menu-item (with same value) is rendered later and slotted into the picker - the default displayed label is not updated and doesn't reflect the related menu-item. Also the menu-item is not selected.
