How to save style tag??

[willian-leme-instar]

I'm experiencing an issue where the HTML Purifier is removing <style> tags even when explicitly allowed in the configuration.

Configuration

        'editor_html' => [
            'HTML.Doctype'             => 'HTML 4.01 Transitional',
            'HTML.AllowedElements'     => 'abbr,b,blockquote,br,code,div,em,h1,h2,h3,h4,h5,h6,hr,i,li,mark,ol,p,pre,s,small,span,strong,sub,sup,table,tbody,td,tfoot,th,thead,tr,u,ul,style',
            'HTML.AllowedAttributes'   => 'title,width,height,colspan,rowspan,class,id,style',
            'HTML.ForbiddenAttributes' => 'on*,style=expression',
            'HTML.Trusted' => true,
            'Attr.AllowedFrameTargets' => ['_blank'],
            'AutoFormat.AutoParagraph' => false,
            'AutoFormat.RemoveEmpty'   => true,
            'URI.SafeIframeRegexp'     => null,
            'CSS.AllowedProperties'    => '*',
            'CSS.AllowTricky'          => true,
            'CSS.Proprietary'          => true,
        ],

Steps to Reproduce

Clean content containing style tags:

$clean = Purifier::clean('<style>p {color: red;}</style><p>Test</p>');

Output shows style tag is removed:

<p>Test</p>

Expected Behavior

<style>p {color: red;}</style><p>Test</p>

Troubleshooting Attempted

• Added style to HTML.AllowedElements
• Enabled HTML.Trusted
• Set CSS.AllowedProperties to *
• Cleared config cache (php artisan config:clear)
• Tried custom element definition

Additional Information:

• PHP Version: 8.2
• Server Environment: Homestead/Laravel Sail

Relevant Packages:

• laravel/framework v11.0
• mews/purifier v3.4.2
