title: How do I set a width for the TextAreaAutoSize component in Material-UI?
body: <p>I can't find any info anywhere on how to change the default width of a TextAreaAutosize component in material-ui.</p>
  
  <p>It seems the only choice is to have this little box.  Does anyone know of a better text area auto size component I can use, or how to change the width of the TextAreaAutoSize component?  </p>
  
  <p>The API doesn't show any properties that have anything to do with 'className'.  I tried to use it anyway and it was ignored.  I also tried wrapping the component in a Box, and styling that, but it was ignored by the TextArea.</p>
  
  <p>Any help would be greatly appreciated!</p>
