Testing version: 0.1 (2934) MacOS
What were you doing: Export
What feature did you use: Any of the new export
What happened: Export pane is in light mode and turns off dark mode for all other windows as well (not editor content though)
What did you expect to happen: Keep dark mode everywhere as normal app behaviour.
App restart will reset to app dark mode.
Toggling dark mode in OS System Preferences will set Export pane (if open) and all other panes to dark mode, but next time you open Export it’s back to light mode and same for all other panes.
