How to remove a value from the Extension.Store of another hierarchy

[bjmi]

Given an extension that implements InvocationInterceptor and AfterEachCallback.

public <T> T interceptTestClassConstructor(Invocation<T> invocation,
                                           ReflectiveInvocationContext<Constructor<T>> invocationContext,
                                           ExtensionContext extensionContext) throws Throwable {
    var store = extensionContext.getStore(MY_NAMESPACE);
    store.put("mykey", "myvalue");
    return invocation.proceed();
}
public void afterEach(ExtensionContext extensionContext) {
    var store = extensionContext.getStore(MY_NAMESPACE);
    var removed = store.remove("mykey") // removed is null
    var value = store.get("mykey")      // value is "myvalue"
}

The store in interceptTestClassConstructor(...) stems from a ClassExtensionContext and the store in afterEach(...) from a MethodExtensionContext.

What would be a proper solution to remove the value from the store in afterEach(...)?
(BeforeEachCallback can't be used as some statements are already executed in the constructor of the test instance.)

You can access the parent ExtensionContext via ExtensionContext.getParent() and, if it's present, its store. If required, you can apply this until you reach the root context.
