Theme reverts to default when page is reopened

[Alc-Alc]

Not sure if it's a feature request or issue or a config issue

Steps

1. Visit https://shibuya.lepture.com/
2. Change the theme to something that is not default (eg: if you are on light mode, change to dark mode and vice-versa)
3. Close the page
4. Reopen the page and notice that the theme is reverted (not the one you selected)

Thanks

Not sure if this is a conscious decision you made but I think the following should be stored in localStorage not sessionStorage?
