+// This test simulates the following situation: |
+// 1. The browser process sends the navigation preload request to the server. |
+// 2. In SW's FetchEvent handler: |
+// 2.1 Executes GC with internals.collectGarbage(). |
+// 2.2 Sleeps 100 ms not to cancel the navigation request before the server |
+// returns the preload response. |
+// 2.3 Returns a dummy response "hello". |
+// 3. The server returns the preload response, and the SW recieves it via the |
+// browser process. |
+// Before https://crbug.com/702527#c9, |m_pendingPreloadFetchEvents| of |
+// ServiceWorkerGlobalScopeProxy is accidentally cleared in the GC. So the SW |
+// crashed when it receives the preload response. |
