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',
)

Start with the pdo_dblib statement handling exercised by the provided PHP reproduction, focusing on how fetch() behaves for two statements sharing one connection. Reproduce the interleaved queries and verify that each statement returns its own A or B rows in the expected order.
