Test page

# Steps to reproduce:

1. Open attached test page by Safari.
2. Click "create new blob" button, then a blob is created and displayed.
3. Click "put" button, then the blob is saved on IndexedDB.
4. Close Safari and open it again.
5. Click "get" button.
6. Click "show" button to make sure the blob is restored and displayed correctly.
7. Click "put" button.
8. Click "show" button.

# Expected behavior:

The blob is displayed correctly, as 1024x1024 image.

# Actual behavior:

The blob is not displayed.
The following error appears in the console.

```
Failed to load resource: The operation couldn't be completed. (WebKitBlobResource error 1.)
```

I have tested in Safari on iOS 13.7, 14.5, 15.2 and macOS 12.1, and confirmed this behavior in all of them.
Note that on the macOS it only occurs occasionally, and on the others it does almost always.
