         Note that this policy blocks JavaScript based on whether the origin of the top-level document (usually the page URL that is also displayed in the address bar) matches any of the patterns. Therefore this policy is not appropriate for mitigating web supply-chain attacks. For example, supplying the pattern "https://[*.]foo.com/" will not prevent a page hosted on, say, https://example.com from running a script loaded from https://www.foo.com/example.js. Furthermore, supplying the pattern "https://example.com/" will not prevent a document from https://example.com from running scripts if it is not the top-level document, but embedded as a sub-frame into a page hosted on another origin, say, https://www.bar.com.
