Current behavior

currently here: https://angular.io/api/core/ChangeDetectorRef#reattaching-a-detached-component the example provided in the last section is just a duplicate of previous section (detach change detector)

Expected behavior

the section about reattaching change detection should feature relevant code sample

Minimal reproduction of the problem with instructions

go here: https://angular.io/api/core/ChangeDetectorRef#reattaching-a-detached-component
observe duplicate sample and not relevant sample

What is the motivation / use case for changing the behavior?

confusing documentation. even if this is a minor issue.

Confirmed
https://angular.io/api/core/ChangeDetectorRef#detach-change-detector-to-limit-how-often-check-occurs
has the correct example for that section.

https://angular.io/api/core/ChangeDetectorRef#reattaching-a-detached-component repeats that same example instead of showing a new example for attaching.

Quick summary of options:

1. Minimally, we need to remove where example is duplicated into incorrect section.
2. Next LOE is to see if we have the right example ready to insert here. If so, insert existing docregion. If not, see 3 below.
3. If there is no existing example to insert, then--after doing 1 and 2--this becomes a feature request for a new example.

@jbogarthyde Hi. I see that you updated API doc for ChangeDetectorRef in July. When you get a chance, could I ask you to take a look at this? Thanks!
