How to pass sessionVariables

[MarkusKramer]

With the JDBC mysql driver I can specify session variables like this

jdbc:mysql://${db.host}:${db.port}/${db.database}?sessionVariables=sql_mode=ANSI_QUOTES

However

r2dbcs:mysql://${db.host}:${db.port}/${db.database}?sessionVariables=sql_mode=ANSI_QUOTES

doesn't switch the session to ANSI mode. Can this be done with r2dbc-mysql?
