Q&A icon images "Updates available" and "No updates" fail to load (floating bug)

When in branch Q&A icon images "Updates available" and "No updates" fail to load when the page is either refreshed several times or during browsing pages.

Easiest steps to reproduce:
1. Open the branch where both of these images are available - read/unread Q&A topics (required condition);
2. Press F5 several times (up to 5) until the bug occurs.

AR: Images don't load sometimes.
ER: All topic status images load correctly when the page fully loads.
