Ability to access underlying Set in combobox #183
Description
Describe the problem
It's currently painful to make a wrapper component that supports combobox with both multiple: true and multiple: false, due to having to handle combobox.value being posisbly a Set or a single value at every turn.
I am aware that valueAsString exists, but that's a bit too simplistic to support all use cases. Eg. in my app, I have to enrich selected values with more info from the data source.
Describe the proposed solution
Expose the internal #value or a pared down version of it that allows for multiple-agnostic manipulation of the selected value. I'd prefer not to have to set up my own SelectionState over the exposed state, as that feels silly!
