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.
