Textarea resizing when scrolling

When scrolling a view with a textarea, the text area changes height while scrolling. After scrolling the original height is restored. This happens both in the Chrome device emulator and on iOS/Safari. See video for example:

This example is based on the tabs example application

   <ion-content class="padding">

      <div class="list">
        <label class="item item-input">
          <textarea rows="10" placeholder="Write something then scroll the view while the textarea is focued"></textarea>
        </label>
      </div>

    </ion-content>

Note that you have to enable the device emulator in Chrome to reproduce the problem. You can find the full source here: http://codepen.io/moberg/pen/myyYMJ

Anyone knows how to make the textarea preserve its size while scrolling?
