title: How to display the full text in the button ipywidget?
body: <p>I am creating an <code>ipywidget</code> button with some text. But the full text is not shown in the button:</p>
  
  <p><a href="https://i.stack.imgur.com/ObqU9.png" rel="noreferrer"><img src="https://i.stack.imgur.com/ObqU9.png" alt="enter image description here"></a> </p>
  
  <p>The code I have used is as follows:</p>
  
  <pre><code>import ipywidgets as widgets
  from IPython.display import display
  button = widgets.Button(
      description='Test button with some text.',
      disabled=False,
      display='flex',
      flex_flow='column',
      align_items='stretch'
  )        
  display(button)
  </code></pre>
  
  <p>What options to use so the full text is shown in the button (i.e. to make the button width increase so the full text is shown)?</p>
