The Precomposed Inline-level Display Values section defines the following <display-legacy> keywords:

• inline-block: Behaves as inline flow-root.
• inline-table: Behaves as inline table.
• inline-flex: Behaves as inline flex.
• inline-grid: Behaves as inline grid.

However, <display-legacy> allows a 5th possibility: inline-list-item.

According to the summary table, it should be

• inline-list-item: Behaves as list-item inline flow.

Or, to maintain a similarity among all these definitions, the equivalent

• inline-list-item: Behaves as inline list-item.
