     41 * This test verifies the initialization, indexedDB.open(), and
     42 * indexedDB.deleteDatabase() aren't blocked when there are unexpected files
     43 * which haven't been deleted due to some reasons. Normally, we expect every
     44 * delete operation works fine. Hoever, it's reported that there is only a
     45 * directory without a corresponding database. It's probably because the delete
     46 * operation fails for some reasons. P1 introduces the mark-file to let the
     47 * future operation understand whether there might be unexpected files in idb
     48 * directory. And, this test verifies these three things work fine if a
     49 * marker-file, a databse file, and a directory exist in current idb directory.
