Consider the following Pulumi program:
```typescript
class MyResource extends pulumi.CustomResource {
// ...
}
class MyComponent extends pulumi.ComponentResource {
constructor(name: string) {
super("myComponent", name);
this.child = new MyResource("child", {}, {parent: this});
}
}
// Create a component resource. The constructor returns promptly, but
// the registration of the component itself happens asynchronously.
// Similarly, its child resource's constructor returns promptly, but
// its registration happens asynchronously. The SDK guarantees that the
// latter happens after the former by waiting on the parent's URN prior
// to registration (note that this is necessary in order for the runtime
// to fill out the `parent` field of the registration request).
const component = new MyComponent("component");
// Create a resource that depends on the component resource. The
// registration of this resource happens asynchronously, and races with
// the asynchronous registration of the component's child.
const res = new MyResource("resource", {}, {dependsOn: component});
```
Due to the races described in the comments, even when all of a
component's children are constructed prior to exiting the component's
constructor (e.g. not in applies, thens, etc.) we cannot guarantee that
the children have been registered prior to any resources that depend on
the component. Because of this, the approach that #7788 takes for
expanding dependencies on components to dependencies on their children
is not necessarily reliable, as it only adds children that appear prior
to dependents in the snapshot.
These changes adjust the dependency graph to add all children of a
component that would not create cycles in the dependency graph.
Fixes #7833.
