On FreeBSD notifications are only delivered using RecursiveMode::Recursive

[GyulyVGC]

System details

• OS/Platform name and version: FreeBSD 13.2
• Rust version (if building from source): 1.74.1
• Notify version (or commit hash if building from git): 6.1.1

What you did (as detailed as you can)

I was watching in NonRecursive mode a directory containing a single file.

What you expected

I expected to get notifications on file changes.

What happened

No notifications were delivered.
I fixed the issue by setting RecursiveMode::Recursive, even if the folder just contain a simple file (no nested folders).
This only happens on FreeBSD... maybe a problem with kqueue?
