title: Let widget silently overflow outside screen
body: <p>How can I make a widget (<code>MarkdownBody</code>) in a <code>ListView</code> silently overflow horizontally outside the screen if the content is too long to fit on the screen?</p>
  <p>I've tried using <code>ClipPath</code>, <code>OverflowBox</code> and a few other solutions, but I couldn't get any of them to do what I want to do. No matter what I try, either the <code>MarkdownBody</code> wraps its content to two lines or I get an overflow error.</p>
  <p>Is there a way to simply make the widget silently overflow and paint itself outside the screen without generating overflow errors?</p>
