Link to and [Read More] missing for long Forum posts on Activity stream page

[henrybcn]

On activity stream page, long texts from a Forum post do not show a Load More nor a link to that forum post. This makes finding and reading long forum entries difficult. The Load More exists for Activity posts, and should exist also for Forum streams.

A Forum post in Activity Stream: no Load More and Link

<li id="activity-N" class="groups new_forum_topic">
<div class="activity-avatar">
<div class="activity-content">
<div class="activity-header">
<div class="activity-inner">
<p>loooooong text […]</p>
</div>

A Activity update post in Activity Stream: it includes Load More and Link

<li id="activity-N" class="groups activity_update">
<div class="activity-avatar">
<div class="activity-content">
<div class="activity-header">
<div class="activity-inner">
<p>
looooooong text…
<span id="activity-read-more-N" class="activity-read-more">
<a rel="nofollow" href="​http://example.com/activity/p/N/">[Read More]</a>
</span>
