Description

After disabling custom colors in the theme's functions.php file, users are still able to select pre-defined gradient backgrounds for list blocks.

Step-by-step reproduction instructions

1. Install and activate a theme
2. Install and activate the Gutenberg plugin
3. Disable custom coloring in the theme's functions.php file:
   add_action( 'after_setup_theme', 'disable_custom_colors' );
function disable_custom_colors() {
add_theme_support( 'disable-custom-colors' );
add_theme_support( 'disable-custom-gradients' );
add_theme_support( 'editor-color-palette' );
add_theme_support( 'editor-gradient-presets', [] );
}

Expected behaviour

Coloring options for all blocks should be disabled.

• Pre-defined text color
• Custom text color
• Pre-defined solid background color
• Custom solid background color
• Gradient background color
• Pre-defined link color
• Custom link color

Actual behaviour

Pre-defined background gradients are not disabled for list blocks.

It looks like this may have been fixed with the release of Gutenberg 10.8.

Hi @nasajones, thank you for reporting this issue it was fixed in #32358, and on the next Gutenberg release the issue should not be preset.
