With Sage v9-alpha3, I’m seeing flash of unstyled content on initial page loads on both dev and proxy urls. I am using MAMP. Clean Sage install. No plugins. WP v4.6.1.
Receiving error for missing stylesheet: http://localhost:3000/wp-content/themes/sage/dist/styles/main.css
But, my styles are obviously showing on each change.
My settings (as followed from github repo):
"publicPath": "/wp-content/themes/sage/",
"devUrl": "http://mysite.dev:8888",
"proxyUrl": "http://localhost:3000",
"cacheBusting": "[name]_[hash:8]"
