[Bug]: Driver Session not working

[Quetlo]

Bug report requirements

• I have confirmed that this is a bug and not a configuration/user error.
• I have searched for existing issues and confirmed that my issue has not been reported before.

IconCaptcha version

4.0.3

PHP version

8.0

Browsers affected

Google Chrome

Expectation

When we click on an image, the backend should not retrieve an error 500.

Actual behaviour

The backend crashes on a division by zero after a click on an image. I suppose count($this->session->icons) should never be 0.
Implementation was done using tutorial steps, except that the domain of the backend is different from the frontend.

Here is the trace :

Array
(
[0] => Array
(
[file] => vendor/fabianwennink/iconcaptcha/src/Challenge/Challenge.php
[line] => 232
[function] => determineClickedIcon
[class] => IconCaptcha\Challenge\Challenge
[type] => ->
)

[1] => Array
    (
        [file] => vendor/fabianwennink/iconcaptcha/src/Request.php
        [line] => 119
        [function] => makeSelection
        [class] => IconCaptcha\Challenge\Challenge
        [type] => ->
    )

Relevant log information

It appears that the session id returned in the first captcha load response header is not used for the verification request; so the session is simply not working.
The problem is that the first php session id is only returned through the first call via XHR.
Thus the browser does not use it as main session cookies for the next XHR.
A very good solution would be a hook to retrieve the php session id from the load call, and an option to set the session id to use for the next calls.

Additional information
