* FEATURE: allow plugins and themes to extend the default CSP For plugins: ``` extend_content_security_policy( script_src: ['https://domain.com/script.js', 'https://your-cdn.com/'], style_src: ['https://domain.com/style.css'] ) ``` For themes and components: ``` extend_content_security_policy: type: list default: "script_src:https://domain.com/|style_src:https://domain.com" ``` * clear CSP base url before each test we have a test that stubs `Rails.env.development?` to true * Only allow extending directives that core includes, for now
