As mentioned in 859594 it is not possible to store blobs in IDB if network service is enabled. But unfortunately this is not caught in any currently automated tests, as this is only broken with chrome/browser_tests, while it "works" in content_shell/content_browsertests.
But running for example http://web-platform.test:8000/IndexedDB/nested-cloning-small.html in chrome with network service enabled clearly shows that this is broken.
No idea how many other layout tests are broken in chrome currently undetected since we only run them in content_shell...
