When I load pages that have their own dark mode enabled the first try usually displays incorrectly as seen from the attached pictures.

Note: couldn't get image upload to work so here are direct links to images. First Load displays like this https://imgur.com/TykSE0A After Reload displays correctly https://imgur.com/Lfjejhr
