# Bug Report

**Ionic version:**

[ ] **4.x**

**Current behavior:**

Pointer cancellation criterion is not accomplished on Ionic main components, while a click is released out of the button target space the click action is triggered.

**Expected behavior:**

The click action should be cancelled and not triggered giving the user the possibility to cancel the tap.

**Steps to reproduce:**

1. Create a new "tabs" app and run it.
2. Tab onto a tab but release the finger out of the tab bar.
3. Error behaviour: the tab changed.
4. Successful behaviour: the click is not triggered and the tab is not selected.

```
ionic start myApp tabs --cordova
cd myApp
ionic cordova platform add ios
ionic cordova build ios
```
