Modifying files with only types doesn't trigger rebuild. No errors thrown by fork-ts-checker-webpack-plugin.

I'm using rspack + fork-ts-checker-webpack-plugin with a pretty simple configuration:

const isDev = true;
const isHot = true;

module.exports = {
    target: 'browserslist',
    mode: isDev ? 'development' : 'production',
    entry: path.resolve(__dirname, 'src/main.ts'),
    context: path.resolve(__dirname),
    devtool: isDev ? 'cheap-module-source-map' : false,
    output: {
        filename: isHot ? '[name].js' : '[name].[contenthash].js',
        assetModuleFilename: '[name][ext]',
        clean: true,
        scriptType: 'module',
        ...
    },
    devServer: {
        host: 'localhost',
        port: 4200,
        headers: { 'Access-Control-Allow-Origin': '*' },
        open: false,
        compress: false,
        client: {
            overlay: {
                errors: true,
                runtimeErrors: false,
                warnings: false,
            },
        },
        hot: isHot,
    },
    plugins: [
        isHot && new RefreshPlugin(),
        new ForkTsCheckerWebpackPlugin({
            typescript: {
                configFile: path.resolve(__dirname, './tsconfig.app.json'),
                mode: 'write-references',
            },
        }),
    ...
};

The problem is, if I make a change to a file that only contains type, like a .d.ts file, no rebuild will be triggered, and I assume therefore, fork-ts-checker-webpack-plugin will not know to run either. Interestingly, the browser DOES refresh when I make a change.

This contrasts with the behavior of webpack-dev-server with fork-ts-checker-webpack-plugin, which responds to all file changes.
