Context

I’m using Zensical to document my Godot plugin. I have a nested “Getting Started” section with multiple child pages (Installation, Prerequisites, Quick Start). I’m not sure if this behavior is a bug or something I’m doing wrong, so I’d appreciate guidance or a workaround.

Bug description

Clicking a child page (e.g., getting-started/installation.md) opens the page correctly. However, if I click the same active page again, it navigates to the parent folder (getting-started/) instead of staying on the page.

I expected that clicking an already active page would leave the user on the same URL, without jumping to the parent.

Reproduction

I’m not attaching a .zip reproduction file.
But I am attaching my current zensical.toml configuration for reference.

Steps to reproduce

1. Create a nested navigation section in zensical.toml with a parent folder and multiple child pages.
2. Start the local Zensical server (zensical serve) and open the site in a browser.
3. Click a child page (e.g., getting-started/installation.md) — it opens correctly.
4. Click the same active child page again.
5. Observe that it navigates to the parent folder instead of staying on the page.
