Image on Featured Product block cannot be removed

[Aljullu]

Describe the bug

While it's possible to change an image when using the Featured Product block, it's not possible to remove once added and leave the default background.

To reproduce

1. Add a Featured Product block.
2. Add an image to the block.
3. See how there's not an option to remove it.

Expected behavior

There's no button to remove it, just to switch it. We'd want an option to remove the image.
