Using the Fish shell, task name tab-completion includes whitespace and the task's description

Description

Since at least 3.46.1, the fish tab completion isn't working as expected. In the below example, I used tab-completion for the task name in the third command.

$ cat Taskfile.yml
# yaml-language-server: $schema=https://taskfile.dev/schema.json
version: "3"

tasks:
  default:
    desc: "Default task"
    cmds:
      - echo "Hello, World!"
$ task --list
task: Available tasks for this project:
* default:       Default task
$ task '* default:       Default task' 
task: Available tasks for this project:
* default:       Default task
task: Task "* default:       Default task" does not exist

The problem is the new sed expression in this commit 655e834

Edit:

The problem actually appears to be related to the use of \s instead of [[:space:]] on macOS. The changes in the aforementioned commit just brought it to the surface.
