title: Double change bar issue
body: <p>I have a document where I create a change bar using <code>&lt;for:change-bar-begin&gt;</code> and <code>&lt;for:change-bar-end&gt;</code>.</p>
  <p>It creates a normal change bar in usual cases, but if there is a table inside a list, and that list is inside another list, it creates a double change bar instead of a regular one. List--&gt;List--&gt;Table, for this table double change bar appears.</p>
  <p>How can I resolve this issue?</p>
