I'm using TinyMCE v5 and I'm unable to manually resize the editor by dragging the right-corner. 

here is my setup:

```
<script src="https://cdnjs.cloudflare.com/ajax/libs/tinymce/5.0.2/tinymce.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/tinymce/5.0.2/jquery.tinymce.min.js"></script>

tinymce.init({ 
    selector:'#client_report',
    resize: true,
    theme_advanced_resizing: true

});

<div class="well"  >
<h3>Client's Report</h3>
    <textarea    id="client_report" placeholder="Enter here the latest client's report"   >
    </textarea >
</div>   

```

I tried with and without theme\_advanced\_resizing, but same result.
Any idea on how to fix this? Thank you.
