sidebar item closes when it should stay open

[jeremyriverain]

Describe the bug

When I navigate on my application after the initial load and I click on a sidebar item that is collapsed, it collapses the sidebar item again.

Reproduction

I reproduced the problem on Stackblitz: https://stackblitz.com/edit/vite-smcwhn?file=docs%2Fitem-2.md

The steps to reproduce are the following:

1. Click on "Get Started" link
2. Open the Sidebar
3. Click on "Dropdown menu", then on "Item 1"
4. You are on the "item 1" page. Open the sidebar again. We remark the "Dropdown menu" is collapsed, although I'm on the "item 1" page

The problem appears only during SPA navigation. If I reload completely the page "Item 1", the "Dropdown Menu" inside the sidebar is open as expected.

Expected behavior

In that scenario, the sidebar item should remain open to give more context to the user.

Thanks for working on the bug. It solves the problem on Stackblitz.

That said, on my real project, the bug is partially solved. The project uses multiple sidebars and this seems to be the problem.

I modified my Stackblitz example to show the problem: https://stackblitz.com/edit/vite-smcwhn?file=docs%2F.vitepress%2Fconfig.ts

I tried with rc.3. It works fine. Thanks a lot !
