safe and unsafe are <overflow-position> modifiers per css-align-3 and must accompany an alignment value. Reject them as standalone keywords for align-items, align-self, justify-items and justify-self. The check only applies when these properties are parsed as longhands; their use inside the place-items and place-self shorthands goes through a separate code path and is unaffected. |
