No path completion in fish for `beet import`

[justbispo]

Problem

After enabling the fish plugin to get tab completion, path completion doesn't work. When I press tab, I get all the fieldnames as suggestions instead.

Before enabling, I was getting path completion but no arguments completion.

Setup

• OS: Arch Linux
• Python version: 3.11.8
• beets version: 1.6.0
• Turning off plugins made problem go away (yes/no): no

My configuration (output of beet config) is:
