Dark mode in edge dev not always works fine

hello, with edge dev version 111.0.1661.27 (Official Build) dev (64 bit) the dark mode (edge://flags/Auto Dark Mode for Web Contents) does not work on google maps, nor on google travel, the respective web pages remain with a white background, while with other browsers including edge everything is ok, this why edge dev is not a stable version? what a pity because I really like this browser aesthetically, it is the most beautiful of all
