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.
