In JSDocs notation for index signatures, Object and object should be treated as the same

TypeScript Version: 2.7.0-dev.201xxxxx

Code

/**
 * Test.
 *
 * @param {object.<string, number>} obj An object.
 */
function func(obj) {
	console.log(obj);
}

Expected behavior:

obj should have a index signature as in #15105

Actual behavior:

obj is treated as any

Additional Info:

This was mentioned in the above issue, and it seems to be related to the way Typescript manage Object and object, but in JSDocs, they are treated similar.

Comienza reproduciendo el ejemplo de JSDoc proporcionado con la versión de TypeScript que se está investigando y compáralo con el comportamiento descrito en el issue #15105. Rastrea cómo se interpreta la anotación de la firma de índice de JSDoc y, después, verifica que object.<string, number> asigna a obj una firma de índice en lugar de any.
