Description

Strange issue / interaction with scoped working directories when using cmp with cmp.cmdline.

Steps to reproduce

open nvim with provided config above. :e :tcd /home/user/.local :vsp :verbose pwd ([tabpage] /home/user/.local) - correct, the tab working directory is as it is :enew | lcd /home/user/.config :verbose pwd ([window] /home/user/.local) - whereas it should be /home/user/.config, also note verbose prints [window] in front of it which is correct.

NOTE: getcwd() also prints the wrong tab directory (tcd) instead of the local directory (lcd)

Expected behavior

The lcd should be returned as expected.

Actual behavior

The working directory returned is incorrect.
