MacDown goes to background after switching window in Mission Control

This is from an email I received. Quote:

[W]hen I'm switching between MacDown windows using Mission Control (either the all applications layout or the windows for this application only layout). MacDown then loses its status as active application and the windows falls back behind Chrome in my case. So this means that I always have to do a CMD+TAB after switching MacDown window through Mission Control.

I haven’t upgraded to Sierra yet, so this is not confirmed. Feel free to drop a reply to tell me whether this is consistent on Sierra between setups.
