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',
)

Comienza con el manejo de sentencias de pdo_dblib ejercitado por la reproducción de PHP proporcionada, centrándote en cómo se comporta fetch() con dos sentencias que comparten una conexión. Reproduce las consultas intercaladas y verifica que cada sentencia devuelva sus propias filas A o B en el orden esperado.
