Bogus warning in Qt Creator / TableModel / Delegate

If a TabelModel is referenced in a delegate choice (e.g. by model.display), the Qt Creator code model launches the warning

"Unqualified access: model is implicitly injected into this delegate. Add a required property instead."

The warning is confusing, because it doesn't specify where a required property should be added. It's wrong, because the QML code works as expected. Using e.g. model.display in a delegate is also explicitly encouraged in the documentation.
