PIE window does not match what was set in the New Viewport Resolution setting

Setting the resolution of PIE to 4K Ultra HD results in the new PIE window going very far out of the bounds of 4K. If you are using two monitors the PIE window will bleed over a good bit into the other monitor.

1. In Windows display settings change your Scale to 150% before running the editor
2. In the Play Mode button click the drop down arrow and select Advanced Settings
3. Under the Game Viewport Settings click the Common Resolutions dropdown
4. Select Televisions and then 4K Ultra HD
5. Now play in New Editor Window

Results: The PIE window will expand far past the bounds of 4K (3840x2160)

Expected: The PIE window will fill a 4K screen and not far exceed it

Workaround: This can be fixed by just snapping the window to the top of the screen but it must be done every time you hit PIE
