Diagram gets squashed when containing element is hidden

[mcrampon]

There seems to be an issue with this type of code :

    <div class="diagram_panel">
      <script type='text/jumly+sequence'>
        @found "You", ->
          @message "get", "JUMLY"
      </script>
    </div>

.diagram_panel {
   display: none;
}

When I do a JUMLY.scan() with this code, I obtain this result :

It works well when the diagram_panel is display: block;, but this is not my intended behavior.

I remember I've tried many things for the issue. In the end, I kind of indirectly made what I wanted.

.diagram_panel {
  opacity:0;
}

and then changing 'opacity' value to 0 or 1 instead of controlling 'display' attribute.
In my case, main purpose of doing this was just to hide the division simply, so it was ok.
