Issue number: #19539 

---------

<!-- Please do not submit updates to dependencies unless it fixes an
issue. -->

<!-- Please try to limit your pull request to one type (bugfix, feature,
etc). Submit multiple pull requests if needed. -->

## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->

When an app uses Capacitor, then the platform subscriptions will run
outside of the Angular Zone.

## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->

- The platform subscriptions will run inside of the Angular Zone
regardless if it uses Capacitor or not.

Added an extra `zone.run` within the event listener.

## Does this introduce a breaking change?

- [ ] Yes
- [x] No

<!-- If this introduces a breaking change, please describe the impact
and migration path for existing applications below. -->


## Other information

<!-- Any other information that is important to this PR such as
screenshots of how the component looks before and after the change. -->

Dev build: `npm install @ionic/angular@7.5.2-dev.11698187124.1b7ea660`
