I've provided answers to these questions on TeX.sx. These were mainly
cosmetic fixes, so I wouldn't consider them exactly as bugs. There was
one minor issue in the longtable support which I fixed though.

There is another issue with longtable and captions:
https://tex.stackexchange.com/a/473045/2891 - I haven't fixed that in
the sources yet.

Best regards,
