I right-clicked to inspect it, and it was still "stressed" in the debugger. I almost didn't believe it until I copied and pasted it into a code editor, and sure enough, "dessert" appeared. Oddly, said editor was VSCode, which I believe is Electron-based. They must have some custom way of rendering text.
In the twitter thread they mention that this also affects Electron and likely all Electron-based applications.
>Looks like anything that uses the Electron framework is affected as well since it uses Blink.
