Visual Regressions in Dark Mode

I just upgraded from 3.05 to 3.12, and it's wonderfully dark! However, there are some problems with the dark mode that are making it difficult to use.

  1. There is no visual separator between the metadata panel on the left and the main content area. In general, there are a lot less separators in dark mode. It's more flat.
  2. The "x" close button on the metadata panel is super tiny (only about 1 mm in height). This one is unrelated to dark or light theme. I think it's because have a 4K monitor with Windows set to be 200% in size.
