Hey @dan and dev team,
setting different visibility states for containers only partially works. See enclosed project. The second container is not visible at any breakpoint, though it’s only set to be hidden on mobile and sm breakpoints and to visible from md up.
this bug has already been fixed and will be included in the next beta 
check out my link the same happens with collapse, Bon said it would be fixed, seems like it is now, checkout if you add a video and hide mobile and show on other screens, when you select fullscreen on the video in the browser it will open the largest screen, being a pain here as I would like to be able to disable and have it open in a new window
