Since yesterday, I have been unable to drag a URL and place it inside a folder on my Bookmarks bar. When I click and drag the URL and then release it inside a folder, the URL just floats back to original URL address bar. The same issue occurs when I attempt to drag an existing bookmark and reposition it inside a folder. After this happens, the folder view remains stuck on my display until I click on the Brave menu bar. Strangely, I can drag a URL to the top level Bookmarks bar and I can reposition bookmarks using Bookmark Manager.
