Fixed immediate UI update after Enter on single-item fields (#15825)

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
