We can also do this inline in the useSelect callback and avoid introducing a new selector for just one use case.

Here's a similar example:

isSaving: dirtyEntityRecords.some( ( record ) =>
isSavingEntityRecord( record.kind, record.name, record.key )
),

I want this new selector, it's as useful as hasSelectedInnerBlock and this is a perfect opportunity to introduce it via using it.

Just sharing my personal preference of avoiding adding selector to packages scope, when I can :)

isBlockBeingDragged( state, innerClientId ) ||

@draganescu and I looked into passing the convertToNavigationLinks function down into the child block where the modal could be opened from there, but we couldn't find where the props ended up since they didn't get added to the edit props.

Another option could have been creating a context just for this scenario that the data needed in the child could have access to, but that also seems a little convoluted.

Do you think it's worth looking into modifying the system for inner blocks?

renderAppender: false,
__unstableDisableDropZone: true,
templateLock: isChildOfNavigation ? false : 'all',

} );

const { selectBlock } = useDispatch( blockEditorStore );

useEffect( () => {
if ( hasSelectedChild || hasDraggedChild ) {
openModal();
selectBlock( parentBlock );
}
}, [
hasSelectedChild,
hasDraggedChild,
parentBlock,
selectBlock,
openModal,
] );

useEffect( () => {
setAttributes( { isNested } );
}, [ isNested ] );
