A user, Don, reports a grid layout issue on mobile devices, specifically when the topic-progress-wrapper is docked. The problem arises from a media query that applies a single-column layout on screens smaller than 924px, which disrupts the layout when the progress bar is docked. awesomerobot initially thought the issue was resolved but confirmed it persists when the progress bar is docked. A fix has been proposed in a GitHub pull request 16444, which addresses the layout issue when the progress bar is docked.
