Delay is refreshing ion-list with new content


Hi All,

I am working on a simple app which will display a list of words for a given word in random order. And each time we click next it will display a new set of words. I am seeing this behaviour when I click next I see a new set of words but also the existing ones still in the view and they are removed after some delay. Is there a way by which I can eliminate the delay in refreshing the ion-list with new content?

Here is the codepen :
