Which @angular/* package(s) are the source of the bug?

platform-server, zone.js

Is this a regression?

Yes

Description

When using SSR/platform-server APIS to prerender pages, you can use the Zone.current.scheduleMacroTask() method to trigger the app to be "unstable" until its promise is resolved.

In v16, using the method call doesn't delay rendering to a string until the provided promise is resolved.

Steps to reproduce:

1. Clone v16 repo provided below
2. Run npm install on the project
3. Run ng build
4. Notice the destroy text logged to the console with no other text logged

Steps reproduce v15 working example

1. Clone v15 repo provided below
2. Run npm install on the project
3. Run ng build
4. Notice the object text logged to the console

{
  filename: '/src/content/pages/me.md',
  slug: 'me',
  attributes: {},
  content: '## About Me'
}

6. Notice the destroy text logged to the console

• Tried downgrading zone.js to 0.12.x with no changes in behavior
• Tried removing provideClientHydration() with no changes in behavior
