Is your feature request related to a problem? Please describe.
I like the idea of having the current scope highlighted. But I must admit that I get "annoyed" that only the texts background changes. So depending on the different lines length and empty lines etc this just looks ugly in my very personal opinion.

Describe the solution you'd like
The highlight applies to the full line for the whole length of the buffer like the cursorline does.
I'm afraid that is not simply possible from the current highlight API...

Describe alternatives you've considered
Well, just disable the current scope highlight...
