 // Test which simulates a race condition between a cross-origin, same-process
 // navigation and a same page session history navigation. When such a race
 // occurs, the renderer will commit the cross-origin navigation, updating its
 // version of the current document sequence number, and will send an IPC to the
 // browser process. The session history navigation comes after the commit for
 // the cross-origin navigation and updates the URL, but not the origin of the
 // document. This results in mismatch between the two and causes the renderer
 // process to be killed. See https://crbug.com/630103.
