Description
The 'outline' style of the button block incorrectly inherits the background-image property if a button.color.gradient is used in theme.json. I believe this should be set to none, in the same way as the 'outline' style sets the background-color to transparent, in order for this button style to be an outline button.
See the Pilgrimage TT3 style variation for an example of this:

Step-by-step reproduction instructions
- Enable TT3 and pick the Pilgrimage style variation
- Insert a button block with the 'outline' style
- See that the
background property is inherited from the default button settings:
