Safari start page has a white tool bar when full screen
When not in full screen the start page looks normal but when I put Safari in full screen, the toolbar is suddenly white even though I have dark mode on. On other websites, the toolbar is greyish black. When I have the sidebar on, the sidebar is black while the toolbar is white looking very weird, also all the buttons in the toolbar are the same color as the tool bar making the buttons look invisible but still function when clicked.
