Weird table tag at markdown email

Here's the view:

@component('mail::message')

    @component('mail::panel')
    Some text
    @endcomponent

    @component('mail::button', ['url' => config('app.url')])
    Name: {{$attendee->name}}
    @endcomponent

@endcomponent

Between the panel and the button i get:

<table class="action" align="center" width="100%" cellpadding="0" cellspacing="0" role="presentation">

Does anyone knows the reason for this?
