Drop doesn't keep position on "radical" window resize events
I've found that if you resize the window to a significantly different size in one operation, Drop doesn't reposition itself properly. Such resizing can occur if you open the DevTools like in the screencast, or if you un-maximize the window with the demo open.

Hmm, which browser are you observing this in? Can't seem to reproduce this myself, unfortunately.
Chrome 44.0.2403.130 m. I've just reproduced it.
:disappointed: I can't imagine there being major differences between the various OS versions of Chrome of the same version. I'll try to look into it, but I'm currently at a loss as nothing is coming to mind why this would.

@dandv chrome doesn't fire window resize events correctly when you open dev tools, noticed that across many apps
@kristijanmatic: in this test, the resize event is fired correctly when I open the DevTools via F12 in Chrome 45 on Windows.
