The gulf between web design and web development has widened greatly in the last 8 years. For casual users putting together a website, templated drag-and-drop site generators like Wix and others have replaced this kind of tool. For professionals, there are CSS frameworks and other component libraries that can be used to build complex layouts, and these people aren't uncomfortable with an edit source-save-preview cycle -- nor did existing WYSIWYG tools keep up with the technology here. Most browsers now ship with sophisticated devtools that allow the page's DOM tree and styles to be manipulated in real-time. This made the long tail of display issues debuggable in the browser itself, and is great for when one does want to see how small changes to the source will affect the final layout. Furthermore, some of 'web design' these days goes to single-page apps these days instead of strictly websites, and require a complex toolchain to build anyway.
