I see this bug is fixed on preview version of vue,but I use the lasted version , seams that it still exist.

  "vue": "^3.1.2",
   "vue-router": "^4.0.10"

diff of dom is here:

Steps to reproduce

create two route: / and about

1. switch page / and about on page index and about
2. after repeat two times , error will occured

What is expected?

route can normally switched

What is actually happening?

[Vue warn]: Unhandled error during execution of scheduler flush. This is likely a Vue internals bug.

Closing in favor of https://github.com/vuejs/vue-next/issues/4023 without vue-router
