Vue-router doesn't react on browser history back and forward

[mbarouski]

Version

3.6.5

Reproduction link

I can't provide it since I don't know how to stably reproduce the issue. Hope on some magical guess only.

Steps to reproduce

I have no idea how to reproduce it, even with my application I can't stably reproduce the issue. A couple of days ago I upgraded vue-router from 3.1.3 to 3.6.5 together with vue upgrade from 2.6.4 to 2.7.13. Also, I can see the issue only with the production build.

When the issue takes place, navigation guards beforeEach, beforeResolve, afterEach are not triggered.

⚠️ I noticed that I can stably reproduce the issue in new tab of browser, after refresh issue is not repeated, I will try to make a reproduction project.

UPD: When I use new tab, I use URL https://site.com and internal logic redirects me to https://site.com/en and at that moment router becomes broken for some reason. When I just refresh page, URL already contains locale prefix and router doesn't crash.

What is expected?

Vue-router always reacts on browser history back.

What is actually happening?

In some circumstances, vue-router stops reacting to browser history back, but <router-link>s (and hence router.push) continue working.

Any ideas?

Well... I finally noticed that router becomes broken because of our internal logic related to the locale URL prefix. So closing the issue...
