Some routes leave their components in the router-view after routeLeave when built

[tajnymag]

Version

4.0.0-rc.1

Reproduction link

https://github.com/Tajnymag/vue-route-bleed-poc

Steps to reproduce

1. build the project
2. open in the browser
3. click on the "Table" link
4. click on the "Index" link

What is expected?

All of the elements of the Table route should be removed from DOM and only elements of route Index should be present.

What is actually happening?

Except <h1>, <table> and <button> are appended to the App's body. The word "appended" is important, as the old bleeded components are not removed and so we can get multiple copies of them.

For some reason, it works as expected when ran using the vite's dev server. It suddenly starts bugging out when built and served on your own.

It seems to happen with a dynamic component without the router but can't tell yet where the problem is exactly
