### How To Reproduce
~~~Console
user@laptop:~$ scancode --license --copyright --json-pp uboot-test.json ./drivers/video/console_truetype.c
~~~

I have tested it also with the patches from https://github.com/nexB/scancode-toolkit/pull/3644, but it does not fix the issue.

How do I need to interpret the log output? Is the token `` of the URL optional here? Why is the match for `src/licensedcode/data/rules/cc-by-3.0_1.RULE` with 100% cov not considered?
