`..` has weird semantics

[pranaygp]

.., which should be "1 directory above cwd" seems to actually have different semantics. Moreover, few other issues.

To repro:

1. cd projects
2. clear
3. Run the commands in the screenshot

Issues:

1. After clear, it says I'm in root/, even though I'm actually still in projects/. The ls verifies I'm in projects/ and then lists the files there
2. ls .. should list files in the parent directory, but actually lists files in the current directory (like ls .) which leads me to believe .. has the same semantics of .
3. cd .. says "not a valid directory" even though, it should either (according to issue 2), not change directories and just stay in the current one without an error, or it should actually go to root/ according to standard semantics for this

Known workaround: Refresh 😂
