selectrum doesn't support parent-directory completions in eshell

[DivineDominion]

Selectrum seems to handle ../ + partial filename completions oddly in eshell.

Given this dir structure:

~/
    folder/
    script.sh

And this init.el:

(require 'package)

;; Configure MELVA package repo
(add-to-list 'package-archives
             '("melpa-stable" . "https://stable.melpa.org/packages/"))
(add-to-list 'package-archives
             '("melpa" . "https://melpa.org/packages/"))
(package-initialize)

(require 'use-package)

(use-package selectrum
  :demand
  :init
  (selectrum-mode +1))

Perform these steps:

1. M-x eshell
2. In the eshell buffer, cd ~/folder
3. From here, type ../scr + TAB

Expected:

• Completion to ../script.sh.

Actual:

• Completion to script.sh, which isn't part of the working dir ~/folder.

This also happens when you replace the completion of ../script.sh with a completion of any other file in the parent dir, including other directories.
