0.20.0+ breaks dark mode on Mac terminal

[MaineTim]

I have been using 0.16.0 "in production" successfully since it came out. I updated to 0.20.1 today to get the datatable row_remove functionality, and found that the update breaks dark mode on the Mac standard terminal. I went back and stepped through the versions, and it's 0.20.0 where the change occurs.

Instead of the usual dark mode with correct borders, the window now comes up as white (which is the terminal normal color) with grey text and borders, the only color is the highlighted row, which is now solid green (instead of the yellow background). The vertical sides of an input widget are also "broken".

I know the Mac terminal is problematic to support, but as it was all working fine up til now, I thought I'd report it in case it's something minor that needs to be tweaked. All works fine under iterm2.

If I can be of any help, let me know.
