I have the sidebar on the right displaying widgets. When I reduce the size of my browser window to see how it collapses at smaller screen size, the sidebar jumps down to the bottom, creating the single-column layout as expected, but it does it too soon, while there is more than enough horizontal room. As I continue to shrink the window, it jumps back up to the right side. This repeats about 2 or 3 times before everything finally falls into single column and stays that way around 700px.
I've tried narrowing the size of sidebar and main content, but allowing more horizontal space does not change the broken responsiveness. Any help would be greatly appreciated!
