Gutenberg panel status in v6+ to solve: select( 'core/edit-post' ).getPreference is deprecated since version 6.0. Please use select( 'core/preferences' ).get instead.

// Instead of using this approach to get a single panel status:
const addressPanelStatus = select( 'core/edit-post' ).getPreference( 'panels' )['cardinal-locator-location-address/location-address-panel'];

// Get all the open panels and use a simple indexOf. Ex:
const openPanels = select( 'core/preferences' ).get( 'core/edit-post', 'openPanels' );
const addressPanelStatus = openPanels.indexOf( 'cardinal-locator-location-address/location-address-panel' );
