How to close tab in WebDriver or Protractor

Question

Is there a way to physically close a tab via Protractor or WebDriver?

I know how to switch tabs programmatically, but it does not bring the active tab to the foreground. I can't always tell what is going on in my E2E tests that run on SauceLabs because when I view the screencasts it is showing the tab that I navigated away from, not the active one.

it('should do something in the previous tab', function(done) {
    browser.getAllWindowHandles().then(function (handles) {
        browser.switchTo().window(handles[0]);
        // do something
        expect(something).toEqual(thisThing);
        done();
    });
});

Switch to the newly opened tab. Close the current windows (in this case, the new tab). Switch back to the first window.

browser.getAllWindowHandles().then(function (handles) {
    browser.driver.switchTo().window(handles[1]);
    browser.driver.close();
    browser.driver.switchTo().window(handles[0]);
});
