Windows tap takes long to respond

I've created an Ionic 2 app. Now I have my buttons set up like this:

<button class="my-button" (tap)="doSomething()" tappable></button>

Now the tappable should remove the 300ms delay on a tap.

The ionic docs aren't too great on gestures but here's a demo of how tap should work

The problem I encounter is that, when I build for windows, the buttons still are very slow to respond to a tap event. Why is this? On iOS and Android, they're both very quick.

I thought it might have to do with loading pages after clicking a button but this isn't the case since normal buttons on a page

$ cordova platform version windows
 Installed platforms:
  android 5.0.0
  ios 4.3.1
  windows 4.4.3

Please note that using (click) instead of (tap) doesn't solve the issue.

Edit 1: In the emulator this issue does not occur.
