      Issue Description:

      Under non-executable model and mvel dialect, when modify-block is placed inside a block like if-block in RHS, the modify does not work correctly (rules to be fired by property reactivity are not fired).

          if (<condition>) {
        modify(<fact object>) {
            <property> = <value>
        }
    }

      Additional Information:

      Test cases may include more variants of modify/update with statement blocks.
      Configuration combinations:

      • non-exec-model and exec-model
      • java dialect and mvel dialect
      • modify and update
