When setting the max width setting in the config regular text wraps at the correct width. Link titles on the other hand will extend out past the max width. I believe this is due to the link numbers and associated characters not being accounted for.
This was also an issue for other lines with prefixes, like list lines and quote lines. Thanks for reporting this. The fix is in master and will be in v1.10.0.
