This is a request for WebKit's position on the blocking="render" attribute on <link>, <script> and <style> elements.

This is a new feature currently being proposed to the HTML spec:

- Full proposal: https://gist.github.com/xiaochengh/9404abbecdc3b45c0e9f3d5e99fbc65d

- Discussion at WHATWG: https://github.com/whatwg/html/issues/7131

All current browsers treat stylesheets as render-blocking resources, and do not start rendering the page before they are loaded. This feature extends this mechanism by allowing authors to explicitly mark an external resource also as render-blocking to ensure better page load performance in more cases.
