title: Alt characters can't be typed in textarea when used with bootstrap's modal dialog
body: <p>I am using bootstrap modal dialog. The dialog has a simple textarea and a button. </p>
  
  <p><strong>Issue:</strong></p>
  
  <p>When I switch the keyboard input to Indian languages like Hindi. Characters that are typed with Alt cannot be typed instead they point to shortcuts of firefox.</p>
