phpMyAdmin 5.2.3 export fails with RuntimeException: No statement inside WITH for views containing nested CTEs

When exporting a database/schema from phpMyAdmin 5.2.3, the export fails if a view contains a nested CTE (WITH inside another WITH).

The view itself is valid in MariaDB and can be created, queried, and retrieved successfully using SHOW CREATE VIEW. However, during phpMyAdmin export, phpMyAdmin creates the temporary stand-in definition for the view and then terminates with:

RuntimeException: No statement inside WITH
Because the export terminates at this point, the final CREATE VIEW definitions that phpMyAdmin normally writes near the end of the export are missing from the generated SQL file.

Simple reproduction steps: (MariaDB 10.11.16)
DROP VIEW IF EXISTS test_nested_cte_view;

CREATE VIEW test_nested_cte_view AS
WITH outer_cte AS
(
WITH inner_cte AS
(
SELECT 1 AS id, 'test' AS name
)
SELECT id, name
FROM inner_cte
)
SELECT id, name
FROM outer_cte;

Then perform a SQL export of the database/schema through phpMyAdmin.
The export then terminates with:
RuntimeException: No statement inside WITH

Expected result

phpMyAdmin should successfully export a valid MariaDB view containing nested CTEs and include its complete CREATE VIEW definition in the SQL export.

首先，使用包含嵌套 CTE 的视图和 MariaDB 架构 SQL 导出重现该故障，并以报告的 RuntimeException 作为切入点。跟踪 parser 对临时替代视图定义的处理；当导出完成并包含完整的 CREATE VIEW 定义时，即表示完成。
