Hard to resize windows all the way to the screen edge

1. Open a resizable window
2. Place mouse to the right of the right window edge, but close enough that resizing is still allowed
3. Click and drag all the way to the right screen edge

Expected result: I have resized the window all the way to the right screen edge

Actual result: There's a small gap because the mouse cursor was outside the window when resizing started (window edge and mouse cursor keep their delta)

This works in macOS because the gap between mouse cursor and window frame is reduced to 0 once the user starts resizing.
