Sidebar doesn't work with mobile

[qbereau]

Hi,

First of all, thank you for the awesome work here!

I started to play with salad_ui and i stumbled upon what it looks like a bug which can also be experienced on the demo here for instance: https://salad-storybook.fly.dev/demo/sidebar-six

If you try to access it using a mobile (also using a browser mobile emulation), trying to expand the sidebar doesn't seem to work and does nothing on mobile.

I guess we would expect to have the sidebar appear with the ability to close it.
