Colors (base16) somehow reset after quitting vis

[U-9200]

Problem

Hi!

I noticed a couple of days ago, that if I use iTerm.app, quitting vis results in base16 colors mismatching, besides TERM=xterm-256color and matching colors for the terminal.

Please see the screenshots attached:

iTerm.app

If I use Terminal.app, lauching and quitting vis doesn't result in colors mismatching, but that is somehow expected, according to https://github.com/chriskempson/base16-shell/blob/master/README.md#Troubleshooting Terminal.app can't display colours 17 to 21 properly. Only launching neomutt (using a base16 theme) colors have been somehow reset.

Terminal.app

I'm not sure, if I'm right here, or if I should drop a bug report over at iTerm.app / neomutt / Apple directly...

Best wishes.
