Combination of keys is not working as expected

[sswaroopgupta]

Expected behavior
The combination of keys should work similar to the manual entry of combination of keys

Actual behavior
Tab and Shift+Tab is not coming back to the same control

Steps to replicate

• Run the following script

const { openBrowser, goto, press, inputField, focus, write } = require('taiko');

(async () => {
    try {
        await openBrowser({headless:false});
        await goto("cleartrip.com");
        await write("Delhi",inputField({"placeHolder":"Any worldwide city or airport"}));
        await press("Tab");
        await press("Shift","Tab");
        await write("Bengaluru");
    } catch (e) {
        console.error(e);
    } finally {
        await closeBrowser();
    }
})();

The expected syntax is await press(["Shift","Tab"])
