Description

Function 'getSettings' doesn't store the settings passed to the block editor.

Step-by-step reproduction instructions

1. Install and activate Gutenberg plugin.
2. Install and activate Twenty Twenty-One or TT1 Blocks.
3. Upload and activate sample-settings plugin.
4. Go to edit post page ('post', 'page', or custom post like 'wp_template').
5. Click and add Sample Settings block.

Code snippet (optional)

PHP:

function add_sample_block_editor_settings($settings) {
  $settings['sampleSetting'] = 'sample setting value';
  return $settings;
}
add_filter('block_editor_settings', 'add_sample_block_editor_settings');

'block_editor_settings' -> 'block_editor_settings_all' since 5.8.0.

JSX:

import { store as blockEditorStore } from "@wordpress/block-editor";
import { useSelect, select } from "@wordpress/data";

export default function Edit() {
  const sampleSetting = useSelect((select) => {
    const { getSettings } = select(blockEditorStore);
    return getSettings()?.sampleSetting;
  }, []);
}

Hi, thanks for the issue.

This is not a bug, this is actually the intended behavior. All editor settings don't make sense in the "block-editor" store which is basically something generic enough that can be used in any block editor instance (not WP or post editor specific)

I see.
Thanks!
