Command chaining doesn't work in async functions

[kretschmannj]

I'm trying to call an async page object command in my Nightwatch test but the test is failing. As you can see by the code sample, I'm attempting to chain a couple of .pause commands together but the chaining mechanism is not working. If I remove the 'async' keywords and comment out the 'await' code then the chained commands work. So it seems that using 'async' breaks command chaining. Is there a workaround for this?

Nightwatch test ...

module.exports = {
    'Test Commmand Queue': async function (browser) {
        browser.page.clients.sandbox.simpleTestPageObject().testCommandQueue() // async function
    }
}

page object file ...

module.exports = {
    elements: {},
    commands: [{
        testCommandQueue: async function () {
            this
                .pause(1)
                .pause(1)

            console.log("0001")
            await this.pause(3000, function () {
                console.log("0002")
            })
            console.log("0003")
        }
    }]
}

output ...

Running:  Test Commmand Queue

If I remember well you need to return browser (this) object in each function to make chaining working. Please anyone correct me if I am wrong.
