Previously, single-item fields `maxItemCount: 1` didn’t show updated
values after pressing `Enter` the UI only refreshed on click outside.
This happened because the items list was hidden while
`shouldAutoEditSingleItem` remained true.
This PR updates the render condition to also check `!isInputDisplayed`,
ensuring the items list re-renders immediately after editing.
**Result:** Instant UI updates on Enter with no impact on multi-item
fields.
Fixes#15792
