Fix Safari's white flash between sites in dark mode

Save the following CSS and set it as a custom style sheet in Safari → Settings… → Advanced:

@media (prefers-color-scheme: dark) {
  body:empty {background-color: #161616;}}
@media (prefers-color-scheme: light) {
  body:empty {background-color: #FFFFF;}}

Thanks to u/torsteinvin & u/Willing-Resource-295 for the fix.
