This PR breaks some previewer and preloader, fetcher rules. Maybe the theme > [filetype] as well.
Before we can use { name = "/mnt/*", run = "noop" } to disable preview and preloader for all files under /mnt folder, no matter how deep it's.
But for now we can only use { name = "/mnt/**/*", run = "noop" }.
So maybe you should add a breaking change when v0.4 is released.

I'm surprised this would break some existing rules - if you want to match directories deeper than one level, you should always use **, and the doc has stated this: https://yazi-rs.github.io/docs/configuration/theme#icon

This PR fixes a bug where * and ** were behaving the same way — * should only be used for single-level depth, while ** should be used for multi-level depth (as in your case).

That's true. Thanks for explaining. 😉
