Table aliases not functioning correctly in OUTER JOIN ON condition

Once an alias is created for a table, the table should only be referred to by its alias.

in 10.0.14, the following statement works fine:

SELECT [...]
FROM Table1
LEFT OUTER JOIN Table2 Alias2 ON Table1.ColumnN = Alias2.ColumnN

However, on 10.0.25 and 10.0.29, the statement does not work and has to be changed to:

SELECT [...]
FROM Table1
LEFT OUTER JOIN Table2 Alias2 ON Table1.ColumnN = Table2.ColumnN

I can find nothing in the change log between 10.0.14 and 10.0.25 to indicate that this is intentional.

The database on OpenSUSE is using InnoDB and I believe that the database on ES6 is MyISAM.
