Search "by identifier" in Scrivener's Sync panel is missing

The new searchbox in the dropdown menu for linking a scrivener item to an event in the timeline is much appreciated, but it feels different from any other similar dropdown of Aeon.

For example, you cannot search an item by “EVXX” (where XX is the numeric identifier of the item and ‘EV’ is the identifier prefix)

So, my feature request is: bring feature parity between any dropdown showing items.
