Environment

• OS Version: MacOS Monterrey 12.1
• Node.js Version: v16.13.0
• fast-glob: 3.2.7

Actual behavior

aus@Austins-MBP src % node index.js
[ 'foo/bar.txt', 'foo/ignore.txt' ]
[ 'foo/bar.txt', 'test/baz/.not_this_either.txt' ]
[ 'foo/bar.txt' ]

Results A: Works as expected. Gets all txt files, ignoring any in the test directory.
Results B: Does not work as expected. It does correctly give me all text files in the foo folder, except for the ignored ignore.txt, but it also gives me one of (but notably not all) files in the test directory.
Results C: Works as expected, after making a slight change to the ignore option.

Expected behavior

aus@Austins-MBP src % node index.js
[ 'foo/bar.txt', 'foo/ignore.txt' ]
[ 'foo/bar.txt' ]
[ 'foo/bar.txt' ]

Steps to reproduce

1. See code sample

Code sample

aus@Austins-MBP src % tree -a
.
├── foo
│   ├── bar.txt
│   └── ignore.txt
├── index.js
└── test
    ├── baz
    │   ├── .not_this_either.txt
    │   └── also_no.txt
    └── no.txt

3 directories, 6 files

const fg = require('fast-glob');

const resultsA = fg.sync('**/*.txt', {
    ignore: ['**/test/**/*']
});
console.log(resultsA);

const resultsB = fg.sync('**/!(ignore)*.txt', {
    ignore: ['**/test/**/*']
});
console.log(resultsB);

const resultsC = fg.sync('**/!(ignore)*.txt', {
    ignore: ['**/test/**']
});
console.log(resultsC);
