Coverage fails with collectCoverageFrom using alternate curly braces syntax

[blackholegalaxy]

🐛 Bug Report

Configuring jest collectCoverageFrom with curly braces syntax for file type displays a coverage of 0% with Unknown status.

To Reproduce

In jest.config.js, if we set:

collectCoverageFrom: [
    'src/app/**/*.{ts|js}'
]

also tested with coma (as stated in another closed issue)

collectCoverageFrom: [
    'src/app/**/*.{ts,js}'
]

Please also note, using that kind of syntax:

collectCoverageFrom: [
    'src/app/**/*.{ts}',
]

without alternate, also produces errors.

Run jest:

=============================== Coverage summary ===============================
Statements   : Unknown% ( 0/0 )
Branches     : Unknown% ( 0/0 )
Functions    : Unknown% ( 0/0 )
Lines        : Unknown% ( 0/0 )
================================================================================
----------|----------|----------|----------|----------|-------------------|
File      |  % Stmts | % Branch |  % Funcs |  % Lines | Uncovered Line #s |
----------|----------|----------|----------|----------|-------------------|
All files |        0 |        0 |        0 |        0 |                   |
----------|----------|----------|----------|----------|-------------------|

Expected behavior

We expect the alternate syntax for file type to be allowed.

Additional information

Removing the curly braces and using:

collectCoverageFrom: [
    'src/app/**/*.ts',
    'src/app/**/*.js',
]

displays proper coverage.

Run npx envinfo --preset jest
