Steps to reproduce:

1. Navigate to Content & Data > Blogs, and create a blog entry under Blogs Admin
2. Navigate to Site Builder > Pages, and create a new Content Page
3. On the new Content Page, add the Blogs widget
4. Navigate to the new content page and view the blog entry.

Expected result:
The user can view a blog entry

Actual result:
The user can only view the title and first part of the blog entry. Clicking on the blog title does not expand the blog entry for viewing.

Workaround:
The blog entry is viewable when the Blogs widget is added to a Widget Page instead of a content page.

Tomcat 9.0.17 + MySQL 5.7. Portal GA1 + 7.2 SP1 build 12.
