Missing Tap event while testing with Selenium

[Walibu]

The following DOM Elements get about every second a click from Selenium tests
Between them other actions taking place and the JS engine is quite busy.
<div class="taptest" (tap)="onTap($event)">
</div>
<div class="clicktest" (click)="onClick($event)">
</div>

public onTap(event: any) {
countTaps();
}
public onClick(event: any) {
countClicks();
}

Out of 1000 clicks:

• all (click) events are triggered,
• but at least one (tap) event is missing

Just in case somebody else has same or similar problem.
