[Maria-developers] Missing tests for MDEV-10057 and MDEV-10058

Hello Sergey and Igor, You recently closed MDEV-10057 and MDEV-10058, but forgot to add tests. - MDEV-10057 does not have tests at all. - MDEV-10058 has only the parser related test, but does not have this test: EXPLAIN SELECT * FROM (WITH a AS (SELECT * FROM t1) SELECT * FROM t2 NATURAL JOIN t3) AS d1; Can you please add the missing tests? Adding patches without tests makes merging painful. You never know if a merge (especially an automatic one) breaks something. Thanks!
