Adapter version: 1.12.5

Issue

When multiple connections are received, the debug context of the previous connection(s) cannot be retrieved from the editor.

For larger codebases (tested with WordPress) it seems that both debug contexts are lost resulting in an empty 'Call Stack', meaning the 'Call Stack' window is empty. The first connection is kept paused, whereas the second gets executed without pausing.

Steps to reproduce

Given the following PHP script debug-multi.php:

$a = ['bee', 'tiger', 'bear', 'deer'];
xdebug_break();
var_dump($a);

Step 1
Open a terminal and execute export XDEBUG_CONFIG="idekey=vscode"; php debug-multi.php.
The adapter correctly stops on the line following xdebug_break():

Step 2
Open a terminal and execute export XDEBUG_CONFIG="idekey=vscode"; php debug-multi.php.
The adapter correctly stops on the same line as step 1, but the previous request is shown as "Running" even if it is still paused (shell command has not returned):
