Dashboard Thumbnail Bug

When you turn on “Website password” in your General site Settings, the Dashboard thumbnail permanently stays on the Login Screen. See example images on two website I currently have. You can’t upload a custom thumbnail image and when you turn off the password protection it doesn’t update the thumbnail. If anyone has a solution to solved this issue or if this is a known bug, please let me know. Thanks!
