Activity stream: Focus does not move to updated content

Issue Summary

In activity stream, focus does not move to updated content. 

Steps to Reproduce

1. Navigate to the System dashboard page.
2. Navigate to the "Activity stream" section on the page.
3. With keyboard & screen reader navigate to "Show more activity" link & activate it.
4. Observe that the focus remains on the link itself & don’t move to the updated content.

Actual Results

In Activity stream section, while navigating with keyboard & screen reader when user activate the "show more activity" link, the new activities are dynamically loaded on the page but users are unaware about the same. The focus remains on the "show more activity" link itself.

This will make keyboard & screen reader users difficult to understand the dynamically updated content.
