title: Vertical writing/drawing not working in web view
body: <p>I am using <a href="https://github.com/szimek/signature_pad/" rel="nofollow noreferrer">szimek signature_pad</a> in the web-view of xamarin app. I am able to draw lines or write horizontally but they don't seem to be working vertically.</p>
  <p>Everything works fine in Desktop and Mobile Google chrome browser and signatures work perfect but when I use the same link inside web-view, only dots appear when I try to write vertically. I doubt that may be caused by web-view vertical scroll but cant figure out how to solve this.</p>
