regression in navbar (when upgrading from 1.0.0-beta.6 to 1.0.0-rc.4)

[Fil]

Describe the bug

On https://observablehq.com/plot/ we tried to upgrade vitepress from 1.0.0-beta.6 to 1.0.0-rc.4, and noticed the following regression:

navbar does not always stay put when you click on one of its links; if a panel at the bottom was open, it may close and the link you have just clicked on moves up, making you lose track of where you were.

Here are two short clips that show the difference:

BEFORE (1.0.0-beta.6):

AFTER (1.0.0-rc.4):
https://github.com/vuejs/vitepress/assets/7001/b7450b0f-07ca-4a2e-910c-db04eb1a18f6

Reproduction

run yarn docs:dev from observablehq/plot#1809

open the subnav tabs in the nav pane, click

Expected behavior

clicking on links in the nav pane should not close or open the subnav tabs.
