[Bug] Location is not restored correctly to the right Display and right location

[staalman]

Description

On a multi-Display setup, closed tabs are not restored to the right location: the location on the window on the screen and the Display where it was on before closing.

Steps to reproduce (if applicable)

Restore - in a multi-Display setup using e.g. a laptop and a docking station with two large Display screens (so in total 3 Displays) - a Link Map Node with one or more tabs.
The window/tabs are always restored to the Screen/Monitor that is currently defined by windows as the "Main Display".
It will also always restore in the same, fixed location on the screen, instead of the original location on the screen.

Expected behavior

Restoring Windows with all Tabs at the 'original' location on the screen , and on the screen and the DIsplay where they were before closing them. This is the behaviour of TO that actually really useful in a multi display setup.

Actual behavior

Always restores to Main Display, same location on the screen.
