Glob Pattern for sideEffects in package.json Not Preventing Tree-Shaking

[SyMind]

🐛 bug report

🎛 Configuration (.babelrc, package.json, cli command)

package.json with the following content for a dependency called foo:

{
  "name": "foo",
  "sideEffects": [ "**.css.js" ]
}

Import a side-effect file in my project:

import 'foo/style/button.css.js';

🤔 Expected Behavior

The imported file button.css.js should be included in the production bundle due to the specified glob pattern in sideEffects, which indicates that any .css.js files should not be treated as having no side effects.

😯 Current Behavior

The file button.css.js is being removed from the production bundle, which suggests that the sideEffects property is not working as intended.
