When I try to execute
navigator.webkitPersistentStorage.requestQuota(1024 * 1024 * 1024 * 15, function (bytes) {
console.log(\'Successfuly allocated
I have reported bug to Google. Turns out that max persistent storage quota is indeed 10GB, but documentation saying "As large as the available space on the hard drive" is incorrect.
