Scss with format fragment and prefix function

Hi, I use your plugin in almost every project and like it very much, thanks for that. Now I wanted to test in scss/css fragments, but unfortunately the prefix function is not executed there.

Expected behavior

$svg-sprites: (
    'sprite-client-general-check': '/build/base/spritemap.svg#sprite-client-general-check' 
)

Actual behavior

$svg-sprites: (
    'sprite-client-general-check': "/build/base/spritemap.svg#(sprite) => {
                let segments = sprite.split(path.sep);
                const index = segments.indexOf('assets')

                if (index) {
                    // removes all segments before theme name and the last
                    segments = segments.slice(index - 1, segments.length - 1);
                    // removes segments for asset and icons
                    segments.splice(1, 2);
                }

                return `sprite-${segments.join('-')}-`
            }sprite-client-general-check",

System information svg-spritemap-webpack-plugin: ^3.8.3 => 3.8.3

Minimal reproduction

path: 'htdocs/web/themes/**/assets/icons/**/*.svg',
config: {
        output: {
            filename: 'spritemap.svg',
            svgo: svgoConfig,
            chunk: {
                name: 'spritemap',
                keep: false
            },
        },
        sprite: {
            prefix: (sprite) => {
                let segments = sprite.split(path.sep);
                const index = segments.indexOf('assets')

                if (index) {
                    // removes all segments before theme name and the last
                    segments = segments.slice(index - 1, segments.length - 1);
                    // removes segments for asset and icons
                    segments.splice(1, 2);
                }

                return `sprite-${segments.join('-')}-`
            },
            idify: (filename) => filename.replace(/[\s]+/g, '-'),
            gutter: 0,
            generate: {
                title: true,
                symbol: true,
                use: true,
                view: true
            }
        },
        styles: {
            filename: 'svg-sprites.scss',
            format: 'fragment',
            keepAttributes: true,
            variables: {
                sprites: 'svg-sprites',
                sizes: 'svg-sizes',
                variables: 'svg-variables',
                mixin: 'sprite'
            }
        }
    }

Hi @cascornelissen , thanks for your quick reply. The fragment looks correct but the key has changed and is without prefix. I think it was with a prefix before that. Even if you configured data as the format.

$svg-sprites: (
    'check': "/build/svg/spritemap.svg#sprite-client-general-check"
)
