Misleading error message for `super.instanceProperty`

Take the following code:

export abstract class YaddaBase {
    protected roots = "hi";
}

export class DerivedYadda extends YaddaBase {
    public get rootTests() {
        return super.roots;
    }
}

TypeScript nightly (5.3.0-dev.20230926) reports:

Class field 'roots' defined by the parent class is not accessible in the child class via super.

The error message here is confusing - one might believe that this has to do with accessing a member with a protected modifier, but it is really about accessing an instance field with super. A better error message would be:

'roots' is defined as an instance property and must be accessed through 'this', not 'super'.

We can also provide a quick fix for this error message.

Reproduisez le diagnostic avec le snippet TypeScript et examinez où le message signalé est défini. Le travail est considéré comme terminé lorsque le diagnostic explique clairement qu'une propriété d'instance doit être accédée via this plutôt que super, et que le quick fix proposé a été évalué dans le cadre de l'issue.
