Почему imagemin удаляет содержимое svg файла?

Использую такой taskдля обработки изображений. По сути imageminдолжен сжимать svgфайлы, но в итоге получается, что он просто удаляет содержимое.

До обработки:

После обработки:

gulp.task('build:img', function() {
  gulp.src(path.src.img)
    .pipe(imagemin({
      progressive: true,
      svgoPlugins: [{
        removeViewBox: false
      }],
      use: [pngquant()],
      interlaced: true
    }))
    .pipe(gulp.dest(path.build.img))
    .pipe(browserSync.reload({
      stream: true
    }))
})

На всякий случай прикрепляю содержимое svgфайла:
