Comment (by Roland Haas):

Further complicated by cd not just splitting the given path at / and then walking that list. Instead, unless a -P is given, it removes `./` and `../` bits from the string first: https://pubs.opengroup.org/onlinepubs/9699919799/utilities/cd.html though this behaviour can be changed via use options in .bashrc .
