RSS dashboard widget not showing visuals

Question

I couldn’t manage to make wp_widget_rss_output to show the content without stripping HTML tags. Reference Q&A’s:

But, using the function fetch_feed we can grab the full feed contents. Check also the SimplePie function reference. See comments for details:
