Actual Behavior

Given a <calcite-combobox>, selecting a combobox item triggers the calciteComboboxChange event. However, in the event's handler, the target combobox's value prop does not include the selected item.

Expected Behavior

The target combobox's value prop does include the selected item by the time the calciteComboboxChange emits.

Impact

A workaround is to derive the value from the combobox's selectedItems prop and/or child elements. However it'd be a high level of effort to fix for every combobox instance in our code base. Requesting p0 priority as Field Maps is looking to release with Calcite 3 in a few weeks.
