The child Codex components Select and TypeaheadSearch emit events when interacted with.

• TypeaheadSearch emits input when the user types in the text field, and load-more when scrolling down to the bottom of the list
• Select emits update:selected when the selection value changes

In attempting to cover the component with tests, it appears that update:selected does not get emitted when the selection changes via prefix-searching. It is unclear whether this is broken in the normal state, or if this is an artifact of the way the test is written.

Acceptance criteria

Investigate which events are being emitted under what circumstances and add tests to validate event behaviours where appropriate
