 This ticket corresponds to the bug report in
 https://github.com/WordPress/gutenberg/issues/73157

 When KSES filters are active (via `add_action( 'init', 'kses_init_filters'
 )`), valid non-preset settings in Global Styles are being incorrectly
 filtered out. Specifically:

 - `lightbox.enabled` and `lightbox.allowEditing` for Image blocks

 The issue occurs because `remove_insecure_settings()` only preserved:
 1. Presets (from `PRESETS_METADATA`)
 2. Indirect CSS properties (from `INDIRECT_PROPERTIES_METADATA`)


 **Step-by-step reproduction instructions**

 1. Enable the KSES filters with add_action( 'init', 'kses_init_filters' );
 2. Go to Appearance > Editor
 3. Open the Styles sidebar
 4. Select "Blocks"
 5. Select "Image"
 6. Change the "Enlarge on click" options
 7. Save the changes

 ⚠️ Note how the changes are reverted
