Currently experimenting with Bootstrap 4 beta through the CDN, I have encountered a peculiar issue with the newly introduced d-* class.
Upon trying out a simple div with the class "d-none d-lg-block", it performed as expected, being visible only when the screen width exceeded 992px. However, when I changed the class to "d-none d-md-block", the div remained visible regardless of the screen size I set it to.
Could this possibly be a bug in Bootstrap 4 beta?
