Text between dwplugin is doubbled when editing

[GordonMoeller]

Issue Description

I use the Bootstrap3 template in Dokuwiki. On one Page I use "accordion" to have some texts collapsible. With prosemirror I get the behavior, that the text is doubled. The original text is as text, the double is in a dwplugin class. The code looks like this when viewed in the developer tools:

<pre class="dwplugin" data-pluginname="bootswrapper_panel">&lt;panel title="Anwendungsbereich"&gt;</pre>
<p>The text</p>
<code class="dwplugin" data-pluginname="bootswrapper_panel">
  ::befor
  <span> == $=0
  The text again
  </span>
  </code>

I don´t know what to look for to solve this. On other pages with other plugins that open and close the behavior is as expected without the doubling of the text.

I use Kaos with the newest plugins. I use the Bootstrap3 Template with the Bootstrap Wrapper plugin.

There is also a Mikio Template which uses Bootstrap 4, but I am not sure if I can switch easily.

(Some corrections for layout.)
