Method focus does not exist on type 'Element'.

Hello!

TypeScript Version: 2.1.6

Code

document.querySelector(`#id`).focus(); // Property 'focus' does not exist on type 'Element'
// but this work fine..
const a = <HTMLElement>document.querySelector(`[${this.horizonatalItemAttrName}]`);
a.focus();

Expected behavior: Focus exist on type 'Element'

Actual behavior: Property 'focus' does not exist on type 'Element'

This is correct; focus is a method on HTMLElement, but not on Element itself:

For example, you cannot .focus() an SVGElement which may also be returned from querySelector.
