I just spent a couple weeks working a performance problem with Chrome on MacOS.  I had added the Noto Color Emoji font to generate a PDF of my journal, but hadn't made the causal association.  Setting "Apple Color Emoji" prior to "Noto Color Emoji" in my font-family in CSS fixed the problem.  I don't notice this on any other iteration of Windows, GNU/Linux, MacOS, Edge, Chrome, Safari, Firefox; however Chrome on MacOS is a likely combination to treat seriously. #css #emoji #macos #chrome
