I'm not sure which is the objective of such test.
Could add more assertions? Can we just test the stepped variable to ensure it has steeped correctly?

Why is the timeout required? I think it should be removed.

Could we make the comment smaller?
What about: store the number of removed chars to correctly report meta.cursor ?

As firstline is no longer used, probably it can be removed as variable

The previous fix for cursor management when there are duplicate headers worked for the faseMode parse path, but not for the slow mode parse path (that handles quotes).
This change is more general and works for both parse paths.
I also spotted a bug in handling quotes at the end of the file when the headers change.
Added new tests for both of these issues.
