When enabling AQE with subqueris within a query, the SQL UI may doesn't show metrics and

Here's a reproduce demo:

spark.range(10000).toDF("value").write.parquet("/tmp/p2")

spark.read.parquet("/tmp/p1").createOrReplaceTempView("t1")

spark.read.parquet("/tmp/p2").createOrReplaceTempView("t2")


spark.sql("select * from t1 where value=(select Max(value) from t2)").show()
