Cannot pass any pre-handover KV operations to query at BEGIN WORK point

This transaction:

transactions.run((ctx) -> {

    ctx.insert(collection, docId, initial);

    ctx.query("SELECT * from `default` LIMIT 1");

}); 

fails at the BEGIN WORK point with error:

{"code":5000,"message":"transactional authorization - cause: Transactions are not configured for ATR Bucket"} 

from code https://github.com/couchbase/query/blob/ce919de4316e2b24a7118d0dec5ace910fed789e/execution/txauthorize.go#L91.

There's two things going on here:

1. Query is reading the "txdata" opaque structure which it should not be doing, as raised separately in MB-42412.
2. Query is rejecting the transaction because it already has an ATR entry.  This doesn't make sense, as a major objective of this integration project is to allow existing transactions (which will have an ATR entry) to then run queries.
