Changing permalink structure messes up collapsible sidebar

[h-enk]

Discussed in #839

^{Originally posted by pensivedog July 14, 2022}
In config.toml under [permalinks], setting docs = "/:sections[1:]/:title/" successfully changes the url structure, but then the collapsible sidebar sections automatically collapse on page load, whereas they are expanded by default when the permalink isn't modified.

Can anyone else reproduce and confirm this is a bug?
