bug: tap click cancels gesture when used on button

# Bug Report

**Ionic version:**
[x] **5.x** (5.4.4)

**Current behavior:**
If the `GesturesController` is used on an Ionic button. The ripple-effect does not work anymore.

**Expected behavior:**
The ripple-effect should work in this case.

**Steps to reproduce:**
In my case: Create a directive with the Ionic `GesturesController` and assign it to a `ion-button` or `ion-fab-button`.

**Related code:**

```ts
import { GestureController } from "@ionic/angular";
/* ... */
constructor (private gestureCtrl: GestureController) {}
/* ... */
this.gestureCtrl.create({
gestureName: "long-press",
el: this.nativeElement,
threshold: 0,
onStart: detail => {
console.log("onStart", detail);
this.onStart.emit(detail.event);
},
onEnd: detail => {
console.log("onEnd", detail);
this.onEnd.emit(detail.event);
}
});
```

**Other information:**

I guess it's about event propagation. The ripple effects does not get any clicks. But how to fix this? I already tested some options like `passive`.

https://ionicframework.com/docs/utilities/gestures

Start with the GesturesController usage in the provided directive and reproduce the issue using the linked StackBlitz demo with ion-button and ion-fab-button. Trace how the gesture handles click or event propagation, then verify that the Ionic ripple effect still works while the long-press gesture is enabled.
