'onclick' type of 'this' is wrong

document.body.onclick = function() {
    console.log(this.innerHTML.length);
}

The code works in a browser and worked in typescript@3.0. But in typescript@3.1.0-dev.20180804 it is a compile error:

src/a.ts:3:22 - error TS2339: Property 'innerHTML' does not exist on type 'GlobalEventHandlers'.

3     console.log(this.innerHTML.length);

The value of this should be HTMLElement like it was before, not GlobalEventHandlers.
Detected in fabric and tingle.js on DefinitelyTyped.
