| // Why use "http://localhost" for the baseURL? |
| // |
| // Using `nil` or a `file:` baseURL causes the test to fail. This is because |
| // when LocalDOMWindow::getMatchedCSSRules enumerates the matched rules, none of |
| // them pass the cross-origin check (hasDocumentSecurityOrigin is false for all the |
| // rules). This is because when the CSS parser context is created, the logic that |
| // sets the value of hasDocumentSecurityOrigin does so by calling SecurityOrigin::canRequest. |
| // Peeking inside SecurityOrigin::canRequest, we see why using a `nil` or `file:` baseURL |
| // fails: |
| // |
| // 1. In the case of `nil` baseURL, WebKit turns that into an effective baseURL of "about:blank". |
| // Because "about:blank" is an opaque origin, canRequest returns false. |
| // |
| // 2. In the case of a `file:` baseURL, none of the patterns (OriginAccessPatternsForWebProcess) |
| // match, so canRequest returns false. |
| // |
| // Notably, WK1 doesn't have the same problem. In WK1, if you load a page with a `nil` baseURL, |
| // WebKit turns it into an effective baseURL of "applewebdata://{uuid}", which passes the |
| // isSameSchemeHostPort test in SecurityOrigin::canRequest. |
