Link to OS-specific audio-routing is not working

[TimPietrusky]

When I want to navigate to a specific OS in the audio-routing guide, it will not work.

Steps to reproduce

1. Open https://modv.vcync.gl/v3/guide/
2. Under "Audio Routing" click on "Windows"
3. See that "#windows" is visible for a second in the browser bar until it gets replaced with "#audio-routing" automatically
4. Try to use the https://modv.vcync.gl/v3/guide/#windows directly and see that nothing happens

Expected behavior
I can link to https://modv.vcync.gl/v3/guide/#windows and I see the windows guide!
