It’s broken on Dark Mode. Needs an extra bit of CSS to determine whether it’s in dark mode or not. The top example is just a GIF, so that's whatever - but the bottom example, which is actual text using this CSS trick, flickers white in a way that unfortunately ruins the illusion of the experience with a black background. The code needs to use CSS's 'prefers-color-scheme' to differ between background colours for the effect. This could also be used, for that matter; to auto-invert the 'text' colour. :)
