When I embed a YouTube Video on a web page:

• When I check "Show Related Videos", it does NOT show related videos, but

• When I un-check "Show Related Videos", it shows related videos

Is this supposed to happen, or is it a bug?

The YouTube functionality is implemented by YouTube. WWB only adds a placeholder to the page. So, the software has no control over this functionality.
