`adjust_base` Does not seem to be correctly calculating.

Here is another case where the report seems to calculate something strange: https://github.com/xmldom/xmldom/pull/698#issuecomment-2254651688

Not sure how it is calculated, but when 6 lines and one branch are being removed, they can of course also no longer be hit?

Or am I misunderstanding something?

I even added/extended tests in that commit.

@karfau I agree with you, after taking a look. @rohan-at-sentry is this a bug, or some part of the system that needs better docs?
