Elasticsearch Geo shape search against nested documents - nested

Question

I would like to be able to search against documents using a geo_shape filter (where the geojson is a nested subdocument) and only retrieve the 1 sub document that matched the geographical filter (not the whole document). I think the docs (specifically nested object type and nested query/filter docs) state this is possible using join:false. For some reason I can't get it to work though and I'm convinced it's a user error or lack of understanding.
On ES 90.5 and below is a worked example.
Can someone point me in the right direction please?
Thanks
Clear the deck and create a new index
curl -XDELETE http://es_server.com:9200/test
{"ok":true,"acknowledged":true}
curl -XPUT http://es_server.com:9200/test
{"ok":true,"acknowledged":true}
Set a new mapping for the testtype
curl -XPUT http://es_server.com:9200/test/testtype/_mapping -d '{
"testtype": {
"properties": {
"entities": {
"type": "nested",
"properties": {
"geometry": {
