Ionic TextAreas getting too large

I have some textareas in a ionic-framework-project that are nested in a list. The textarea is not shown fully. A part of it is out of screen.

<div class="list" style="width:100%;">
    <label class="item item-input" style="max-width:100%">
        <span class=input-label>Description</span>
        <textarea required></textarea>
     </label>
</div>

what happens is that the widht of the textarea is getting too big, span.width+textarea.width > 100%.

If I manually set the textarea width down a little bit, it is shown 100%.

I set the max-width of it's parant to 100%, so it shouldn't get larger, but it does.

How can I prevent this behaviour and let the texare not grow over the screen.
