Incorrect SQL generated when use both left join with unrelated entity and implicit join to another entity in select-clause -- still broken on Sybase

This issue is to track the fact that even though https://hibernate.atlassian.net/browse/HHH-11337 was fixed in Hibernate 5.1.4, the affected queries still fail on Sybase and DB2 (and possibly other databases) - see comment https://hibernate.atlassian.net/browse/HHH-11337?focusedCommentId=88106&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-88106

This issue is specifically for fixing on Sybase.

This can be reproduced by running EntityJoinTest.testLeftOuterEntityJoinsWithImplicitInnerJoinInSelectClause against an affected database.
