some global properties missing from window but accessible directly

[ghost]

TypeScript Version: 2.1.1

Code

/**
 * typescript says `[ts] Property 'x' does not exist on type 'Window'.`
 * for all of these, but they all exist and work in browsers:
 */
window.Document
window.eval // <- this one is useful for "indirect eval" - i ran into this bug once earlier
window.EventTarget
window.Function
window.MouseEvent
window.HTMLElement
window.DocumentFragment

/**
 * same thing here, this is more similar to what i was doing when i found this bug
 */
var iframe = document.createElement("iframe");
iframe.contentWindow.Document
// etc etc

// somewhat important note: there are probably more, i just quickly came up with these

/**
 * they work in typescript if accessed this way:
 */
Document
eval
EventTarget
Function
MouseEvent
HTMLElement
DocumentFragment

(you can paste it in the typescript playground here: https://www.typescriptlang.org/play/)

Expected behavior:

there should be no errors, all the properties should exist on window

Actual behavior:

the properties don't exist on window but seem to exist in a "global scope" somehow so they're only visible to typescript when accessed directly

normally i guess i could just not use the window. prefix for accessing these properties, but that's not an option for indirect eval via window.eval or accessing the properties from other windows (iframes, window.opener, window.top, etc)

Unfortunately it's a result of these types being separate to the global scope in TypeScript. You might be interested in a related issue that could improve the situation: #14052. For now, all the definitions would need to be duplicated into window (and global in node).
