iPhone ion-textarea click away works bad

I’m working on iPhone 7 plus, iOS 11 with ion-textarea. When I try to tap away from theion-textarea, in 95% of the cases I need to tap several times for the keyboard to disappear. Is there a good solution to this issue, as the UX gets really bad when you can’t tap away on the first tap.
Thanks!

this.keyboard.close();

put this anywhere outside the textarea and it will work just fine!
