PDO_DBLIB: Fetching from statements sharing a conection results in wrong values being returned

Description

When using pdo_dblib, making 2 queries at the same time using the same conection results in corrupt statements
The keys are correct, but the results are from the last query
It's as if both statements are somehow sharing the same cursor under the hood

The following code:

<?php
$user = "REDACTED";
$pass = "REDACTED";
$host = "REDACTED";
$db   = "REDACTED";

$con = new \PDO("dblib:host=$host;dbname=$db;version=7.3;charset=UTF-8",$user,$pass,array(
    PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC
));

$sta = $con->query("SELECT *
FROM (
    VALUES ('A0'),
           ('A1'),
           ('A2')
) AS MyTable(A)");

$stb = $con->query("SELECT *
FROM (
    VALUES ('B0'),
           ('B1'),
           ('B2')
) AS MyTable(B)");

var_export($sta->fetch()); echo "\n";
var_export($stb->fetch()); echo "\n";

var_export($sta->fetch()); echo "\n";
var_export($stb->fetch()); echo "\n";

Resulted in this output:

array (
  'A' => 'B0',
)
array (
  'B' => 'B1',
)
array (
  'A' => 'B2',
)
false

But I expected this output instead:

array (
  'A' => 'A0',
)
array (
  'B' => 'B0',
)
array (
  'A' => 'A1',
)
array (
  'B' => 'B1',
)

PHP Version

PHP 8.2.7

Operating System

Ubuntu 23.04

从提供的 PHP 重现代码所涉及的 pdo_dblib 语句处理开始，重点关注两个语句共享一个连接时 fetch() 的行为。重现交错查询，并验证每个语句都按预期顺序返回属于自己的 A 或 B 行。
