IE Mode - Edge ignores user preference for popup window position

Hi Kelly,

Thanks for the response. Yes, my preference/expected behavior would be that Edge opens popups in IE Mode respecting the screen boundaries and if the window for some reason opens outside the screen bounds, there should be a way for the user to remedy this for subsequent opens. 

I went back and retested IE and Edge based on your second paragraph. It appears that I was mistaken in my assumption that IE and Edge were remembering the user preference. At least in Edge, the window position is recorded in the preferences file, but this doesn't seem to control where the window will open next. However, both IE and Edge (in Edge mode) correctly respect the screen bounds when opening these popups. 

After a little more testing I think Edge might be opening these windows out of bounds only when multiple displays are present, and not all displays are using the same scaling (such as when an external monitor is connected to a laptop). 

It should be possible to duplicate the issue this way:

1. Set the main display to 125% scaling
2. Connect a 2nd display and set it to 100% scaling
3. Open an Edge window full screen on the 2nd display
4. Invoke the type of popup in IE Mode described in my original post (window.open)

The window will open at least partially offscreen. It may be necessary to change the relative position of the displays in Display Settings to wind up with a configuration that results in an offscreen window. 

Maybe IE Mode is basing the popup position on the main display scaling for all displays?
