I cloned your form and I was able to increase the width. The reason why the width of the form text box is not increasing because the max width is set to 300px only. To change that, please go to the Advanced Form Designer and change the Form Layout Input Width to your own preferences. Here's a screen animation guide:

Hope that helps. Please try it and let us know how it goes. Thank you.
