When you visit https://www.slashdot.com, is Night Mode not working immediately, or not working after you scroll, or not working when you subsequently visit (by clicking a link) another slashdot.com webpage?

When you encounter a “not working” . . . you might toggle the Site-Specifict Brave Shields > JavaScript setting. Does that action cause the Night Mode to work for the site?

On Slashsdot (and all the instances I’ve found), it’s not working immediately, regardless of whether I scroll down.

If I toggle the “Block Scripts” option, the site’s text totally disappears.
