how to keep hash in svg url with webpack encore

Question

I'm using Symfony with webpack encore. I need to use SVG file with multiple icons inside. normally I would do something like background-image: url("icons.svg#search"), but with encore in final css is the hash part removed for some reason and it won't display anything on the web. Is there any way I can keep the hash?

this is my webpack.config.js right now:

const Encore = require('@symfony/webpack-encore');
if (!Encore.isRuntimeEnvironmentConfigured()) {
    Encore.configureRuntimeEnvironment(process.env.NODE_ENV || 'dev');
}

Encore
    .setOutputPath('public/build/')
    .setPublicPath('/build')

    .addEntry('app', './assets/app.js')
    .enableStimulusBridge('./assets/controllers.json')
    .splitEntryChunks()
    .enableSingleRuntimeChunk()
    .cleanupOutputBeforeBuild()
    .enableBuildNotifications()
    .enableSourceMaps(!Encore.isProduction())
    .enableVersioning(Encore.isProduction())

    .configureBabel((config) => {
        config.plugins.push('@babel/plugin-proposal-class-properties');
    })
    .configureBabelPresetEnv((config) => {
        config.useBuiltIns = 'usage';
        config.corejs = 3;
    })

    .copyFiles({
        from: './assets/images',
        to: 'images/[path][name].[hash:8].[ext]',
    })
    .enableSassLoader()
;

module.exports = Encore.getWebpackConfig();
