This is a documented limitation of the current design and implementation of the 'display' property. The ELisp manual says: ‘STRING’ Display STRING instead of the text that has this property. Recursive display specifications are not supported—STRING’s ‘display’ properties, if any, are not used. I never looked into lifting this restriction, so I don't know what would that entail. There are probably some complications with faces, at least. If someone wants to study the issue, that'd be welcome, I think.
