sp-combobox

Description of the requested feature

When there is a list of items, which has itemText and value. Currently, the combobox only supports the itemText to be sent to change event. So any handling needs to be done using itemText.

But is the list of items has duplicate items with same itemText and different value (uniqueId, in our case its projectId). In this case, we would need both itemText and value to be sent to the change event. So the handling can be done based on both the itemText and value, even if the itemText is same, we can use value as differentiator.

So the request here is to, expose an explicit selectedValue property would eliminate reliance on itemText uniqueness and provide a more reliable contract for downstream consumers.

Can you provide an accessible use case for duplicate item text? How would users make the distinction between items with the same item text? What happens when that text is typed in the combobox? Is the first item selected?
