While working on getting our starter app tests running on CI, I ran into
the following error:

```
⎯⎯⎯⎯ Unhandled Rejection ⎯⎯⎯⎯⎯
ReferenceError: document is not defined
⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯
 ❯ Module.startTapClick node_modules/@ionic/core/components/index9.js:133:15
    131|   };
    132|   const doc = document;
    133|   doc.addEventListener('ionGestureCaptured', cancelActive);
       |               ^
    134|   doc.addEventListener('touchstart', onTouchStart, true);
    135|   doc.addEventListener('touchcancel', onTouchEnd, true);
 ❯ node_modules/@ionic/core/components/ion-app.js:21:113

This error originated in "src/App.test.tsx" test file. It doesn't mean the error was thrown inside the file itself, but while it was running.
This error was caught after test environment was torn down. Make sure to cancel any running tasks before test finishes:
```

We are referencing `document` without any "document defined" checks.

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

- Tap Click is only enabled if the `document` is available since we set
event listeners on the document.

## 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. -->

screenshots of how the component looks before and after the change. -->
