Sorry if this isn't the right place for it, but it's the official documentation resource for Android so I assume you report it here?

DESCRIBE THE ISSUE IN DETAIL:

I have the documentation site set as "Appearance: dark theme" (via the page's toolbar) to make it more comfortable to read, especially at night. (Windows 10 set to Dark theme, latest Chrome set to "Device" i.e. dark). When I open a page on developer.android.com, what actually happens is I get a bright white page, and it only goes dark after the page fully loads, which can take several seconds. Navigating around the site in the same tab often produces the same behaviour - bright white page by default, themed sometime later.

What I'd expect (and what every other site with a dark theme seems to do) is for the page to be themed immediately (ideally with no visible flash of white at all) before any content is displayed.
Right now I literally have to avert my eyes when opening a documentation page sometimes so I don't get blinded, feels like a big accessibility issue!


STEPS TO REPRODUCE:
1. Open a page on developer.android.com in Chrome (haven't tested other browsers, I assume it's the same since the browser itself is in dark mode, new tabs are dark etc, other pages display fine)
2. Click the moon icon and set the appearance to "dark theme"
3. Open another page on the site in a new tab (e.g. middle-click a link)
4. Page is not dark
5. Wait a bit
6. Now it is
