I want to declare declare type HTMLElement && HTMLElement.prototype.style.position = 'absoltue' in typescript.

Is it possible?

```
type AbsoluteDisplay = {
  style: {
    position: 'absolute';
  };
};

const testFunc = (arg: ??) => {}; // I want arg type!

const truthyElem = document.createElement('div');
truthyElem.style.position = 'absolute';
testFunc(truthyElem); // Ok

const notAbsoluteHTMLElem = document.createElement('div');
testFunc(notAbsoluteHTMLElem); // No

const falsyElem: AbsoluteDisplay = {
  style: {
    position: 'absolute',
  },
};
testFunc(falsyElem); // No

```
