title: setting non-integer line height in Lighttable
body: <p>Adjusting the line height is a very nice feature of Lighttable. Following the documentation, I'm modifying the User behaviors with:</p>
  
  <pre class="lang-clj prettyprint-override"><code>;; The editor tag is applied to all editors
  :editor [:lt.objs.editor/no-wrap
           (:lt.objs.style/set-theme "default")
           (:lt.objs.style/font-settings "Ubuntu" 12 1.5)
      ]
  </code></pre>
  
  <p>However, I'm getting a quite erratic behavior when putting a <em>non-integer</em> line height (here <code>1.5</code>). When saving the file, the automatic refresh sometimes work, sometimes not. When I put an integer height instead (say <code>1</code> or <code>2</code>), it reloads perfectly.</p>
  
  <p>So I'm wondering: is it allowed to put non-integer line height? Or is there just a bug in the reload process?</p>
