Videos in Bootstrap3 theme mobile view on Firefox are wider than screen.

[NikRusche]

Using the Bootstrap3 theme, on Firefox, on a mobile phone (tried different screen sizes), embedded videos are about 20 % larger than the actual screen, making the mobile view quite less attractive. Using the "full" keyword works as expected (mobile and desktop), but the videos in desktop view take too much space for my liking. Edit: Chrome/Edge seem to have the same problem! Here shown in Firefox on Windows (but the effect is similar on mobile phone Firefox)
