The problem is when user include a large image or header in beginning of a new Topic, the “excerpt” and “Read More” become no longer clickable.
It is because discourse generate lightbox for the image and anchor for header. The
<a> tag included in excerpt break the link.
<a class=\"lightbox\" href=\"\" data-download-href=\"\" title=\"Image title\"></a>
<a name="header" class="anchor" href="#header"></a>
Here is screenshot from Chrome inspector.
