title: Fabricjs textbox for large text content stuck in first line
body: <p>In fabricjs textbox if text content(no space) is larger than the textbox width it won't go to next line, it stuck at first line. So that I get the content width using <code>text:changed</code> event and try to press <code>enter</code> programmatically if content is greater than textbox width but its not working. Is there any other way? </p>
  
  <p>I don't want to override fabricjs default method for breakwords it has other conflicts and cursor get misplaced. </p>
