`symbol` are removed even when they're used in styles

[nhoizey]

Describe the bug

SVGO removes symbols from the SVG even when they're used in styles.

To Reproduce

With this SVG image: https://nicolas-hoizey.photo/ui/logo.svg

SVGO CLI with default configuration removes the <symbol>s, even if they're used in the styles, to make the logo responsive.

It doesn't remove the symbols with this configuration removing the inlineStyles plugin:

module.exports = {
  plugins: [
    {
      name: 'preset-default',
      params: {
        overrides: {
          inlineStyles: false,
        },
      },
    },
  ],
};

Expected behavior

symbols should be preserved, as they're useful in the image.

Desktop (please complete the following information):

• SVGO Version 3.0.2
• NodeJs Version 19.0.1
• OS: macOS 13.0.1

Additional context

I tried first to optimize my SVG in SVGOMG and got the issue, which I referenced here:
jakearchibald/svgomg#417

I think this is related to issue #1834 and resolved by PR #2056 - media queries were being removed by inlineStyles.
