CMIS query containing IS NULL predicate and LEFT JOIN inconsistent between Solr and TMDQ

[Googulator]

The CMIS query
SELECT B.cm:owner FROM cmis:document A LEFT JOIN cm:ownable B ON A.cmis:objectId = B.cmis:objectId WHERE B.cm:owner IS NULL AND CONTAINS(A, '(TEXT:* OR NOT TEXT:*)')
fails to find documents without the cm:ownable aspect. The same query without the magic CONTAINS() to disable TMDQ works:
SELECT B.cm:owner FROM cmis:document A LEFT JOIN cm:ownable B ON A.cmis:objectId = B.cmis:objectId WHERE B.cm:owner IS NULL
