Upgrade to v4.0.6 give xDebug issue

On a working project, if I update to Winter.Debugbar v4.0.6, I ran into a xDebug infinite loop warning when trying to put a model in cache.

How to fix the issue:

• Revert to version 4.0.5
  or
• Comment this line in Plugin.php

  wn-debugbar-plugin/Plugin.php

  Line 58 in 9a709a8

  Config::set('debugbar', Config::get('winter.debugbar::config'));

  
  or
• Replace config winter.debugbar.options.mail with :

        'mail' => [
            // 'full_log' => false
            'timeline' => env('DEBUGBAR_OPTIONS_MAIL_TIMELINE', true),  // Add mails to the timeline
            'show_body' => env('DEBUGBAR_OPTIONS_MAIL_SHOW_BODY', false),
        ],

In this latest case, what I don't understand is having to set the value of options.mail.timeline to true.
If I set it to false, I get the same error.

I noticed that the barryvdh/laravel-debugbar package has been updated from v3.15.2 to v3.15.4.
I'll try to see if this update could be the cause.

Winter.Debugbar	barryvdh/laravel-debugbar
v4.0.5	v3.15.2	OK
v4.0.5	v3.15.3	OK
v4.0.5	v3.15.4	OK
v4.0.6	v3.15.4	NOK

In the first three cases, none of the plugins/winter/config/config.php or config/winter/config/config.php are taken in account

In this latest case, I need to have Winter.Debugbar options.mail config :

    'options' => [
        // ...
        'mail' => [
            'full_log' => false
        ],
        // ...
    ],

replaced by

    'options' => [
        // ...
        'mail' => [
            'timeline' => env('DEBUGBAR_OPTIONS_MAIL_TIMELINE', true),  // Add mails to the timeline
        ],
        // ...
    ],

Nevertheless, options.mail.timeline config need to be set to true.
If set to false, the issue raise again
