Trying out dark mode (Toggle theme button) in Chrome v70, but it’s not working. The menu at the top changes and the body text color changes to white, but the background remains white. I can fix this with Dev Tools by disabling the white background CSS for the #writer textarea.
The CSS I had to disable looked like in-line styling (found under element.style). I disabled:
background: none 0% 0% / auto repeat scroll padding-box border-box rgb(255, 255, 255);
and the dark theme worked!
I’m wondering if this is a bug or some weird extension or an issue with Chrome.
