Child windows opened on secondary monitor appear outside screen bounds (when DPI difference between displays?)

Reported by ross.and...@radn.org, Dec 8 2016

Issue description

UserAgent: Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/54.0.2840.99 Safari/537.36

Steps to reproduce the problem:
I don't know if the DPI difference between the displays is part of the cause, but including that info anyway:

1. Have a high DPI laptop display (e.g. 15" 3200x1800)
2. Have a "normal" DPI external monitor (e.g. 21" 1680x1050)
3. Select "Extend these Displays" as Windows Multiple displays mode
4. Set Developer Tools to open in separate window
5. Open Developer Tools
6. Move Developer Tools window to secondary display
7. Close Developer Tools window
8. Open Developer Tools window again
9. Notice that it is not visible on either display - it is located somewhere outside the bounds of the displays

What is the expected behavior?
When closing the Developer Tools on a secondary display (with different DPI to main display?) then reopening it, it should appear in the same position it was in when it closed.

What went wrong?
When closing the Developer Tools window on the secondary display, it saves its last location incorrectly, or calculates initial position incorrectly when reopening.  The result being that the window opens outside the bounds of the display.

Did this work before? Yes Unknown

ross.anderson@: Could you please confirm if the issue is still seen on the latest stable(55.0.2883.87) as well?

Thanks..
Yes, I can confirm that the issue is still present, windows such as the dev tools still reopen outside the bounds of my screen when last closed on my secondary display.  Attached is spy++ info for the bounds of the window after reopening it.

What is your multiple display layout? (Side-by-side? Top-aligned?)

+----+----+
|    |  2 |
| 1  |    |
|    +----+
+----|

Something like the above would be helpful. Thanks!
Here you go.  Relative scale based on resolution, not physical display size:

   +----------+
   |          |
   |    2     |
   |          |
+----------------+
|                |
|                |
|       1        |
|                |
+----------------+

Windows Multiple display mode: Extend these displays

Display 1:
 - Laptop built in display
 - 15"
 - 3200x1800
 - Windows scaling factor: 200%

Display 2:
 - External display
 - 21"
 - 1680x1050
 - Windows scaling factor: 100%
