// .body attribute of Request and Response object are experimental feture. It is
// enabled when --enable-experimental-web-platform-features flag is set.
// Touching this attribute can change the behavior of the objects. To avoid
// touching it while comparing the objects in LayoutTest, we overwrite
// assert_object_equals method.
