Ensure that side panel doesn't cover main chat area

The side panel covers the main chat area unless the app window is set very wide. For me, the app has to take up over half of my working screen before it allows both the side panel and main panel to be fully viewable. This problem did not occur for the first 2 years or so that I used RC; it just began on 2/22/22. Prior to that date, the window allowed both panels to be fully visible, regardless of app window width.
