List View has incorrect height about marky-mark

[jvanzummeren]

I’m not sure if this is an issue related to MarkyMark, is the same set-up with a multi line UILabel working correctly?

Regards,

Jim

I had the same issue as @christie-alphero but was able to create my own label class that worked around the issue. This is the most wonderful markdown library on iOS, thank you so much for your hard work @jvanzummeren!
