Cannot read property 'end' of null

Line 158 in c9b1e27

start = pos && pos.startTag && position(pos.startTag).end

position(pos.startTag) could return null, but that branch isn't expected by the code that fails.

Did this actually happen in practice?
If so could you share some content that cause this to happen?

[danielepolencic]

Yes, I have an error in the code that led me down that path.
Here's the input: https://gist.github.com/danielepolencic/67013b543f1938858aa68c41095b2156
(I use hast-util-raw to parse that html)

Thanks!
A pull request to address this would be welcome!

[danielepolencic]

I will raise a PR later today. Thanks

Might (Also) be an issue in parse5 if they don't provide the correct positional information 🤔
