Motivation
I have been experiencing crashes in my program approximately every 10 minutes due to #183. I have now investigated and found the problem, reproduced it with a test and fixed the panic. Additionally I was missing some documentation on this behaviour.
Solution
This is fixed by instead of
expect-ing the extension data to instead uselet-elseto match and ignore if it is not present. This behaviour also exists in other implementations in the same file.
