A moderated (hidden) Flow post titlebar, magnified for clarity.

Every topic's titlebar has a
  <div class="flow-topic-summary"> </a>
in it, even there's no summary text.

This has a dotted gray top border, from modules/new/styles/layout.less :
    .flow-topic-summary {
            border-top: 1px dotted @colorGrayLightest;
            ...

The result:

* The dotted border is invisible in a normal topic, because the topic's background is the same @colorGrayLightest.
* In a moderated topic you always see this faint dotted line whether there's a summary or not, because the topic's background-color is white. It looks weird, see attachment
* Slight waste of vertical space in topics without a summary.

What's the intended design?
