Configuration

{
	"presets": [

			{
				"targets": ["chrome 22", "last 12 years"],
				"modules": "systemjs"
			}
		]
	]
}

Current and expected behavior

For SystemJS, Babel does not replace the typeof operator with the @babel/helpers typeof function in toPrimitive in certain scenarios.

At the same time, in the browser, I get the error '@@toPrimitive must return a primitive value' because the Symbol from the polyfill is treated as an object, not as 'symbol'

Environment

"@babel/cli": "7.23.4",
"@babel/core": "7.23.7",
"@babel/preset-env": "7.23.8",
