case-insensitive on isActive property

[Kyle-Ye]

Version

3.5.3

Reproduction link

localhost/active-links/abouT

Steps to reproduce

• Run yarn run dev in the root path of the project
• Go to http://localhost:8080/active-links/abouT

What is expected?

The "/about" will be treated as active.

What is actually happening?

The "/about" is not treated as active.

---

Since Vue Router already supports case-insensitive matching for routes themselves. I think it should be the same for the active match to be case-insensitive too.

Provide a valid repro please

I think using a website like CodePen to build a minimal reproducible environment seems to be low-benifit and troublesome because we can directly use the existing example files（repo's /examples/activeLinks folder and so on） of the repo to reproduce. Just run yarn run dev(or node examples/server.js) and go to http://localhost:8080/active-links/abouT will reproduce the issue

Aah, I couldn't guess you were talking about the repository examples!
