Bug 444756

Not sure if intended or not but when having `save display's properties for only this specific display arrangement` checked, it does not link/save the global display scaling setting with the display arrangement.


I was thinking that global display settings could be automatically changed whenever I plug in/unplug a monitor 
1. Have one monitor plugged in with 100% display setting saved with `save for only this specific display arrangement`
2. Plug in second monitor
3. Enable `save for only this specific display arrangement`
4. Change global display % setting to not 100%
5. Unplug monitor
6. What should happen is that it changes back to 100% display scaling because I thought it was saved when using `save display's properties for only this specific display arrangement

Instead, the global display scaling setting does not change when plugging in/unplugging monitors.
