    Description

      The behavior of the OR operator in the IF condition has changed from MariaDB 10.2 to 10.3.
      now I noticed that the following syntax doesn't work in SELECT statements anymore: 

      SELECT * FROM tab t WHERE IF(@a = 1, t.a = 1 OR t.b = 1,1=1)

      Now I'd have to write:

      SELECT * FROM tab t WHERE (IF(@a = 1, t.a = 1, 1=1) OR IF(@a = 1, t.b = 1, 1=1))

      Is it a bug or a deliberate change? Is there a setting with which I can reactivate the previous behavior?
