### Issue Details

* **Electron Version:**
  * 6.0.6, 6.0.12
* **Operating System:**
  * Microsoft Windows [Version 10.0.18362.418]
* **Last Known Working Electron version:**
  * 6.0.5

### Expected Behavior
minHeight/minWidth is the same value on all monitors

### Actual Behavior
minHeight/minWidth are much larger in size on lower DPI monitors

### To Reproduce
Sample app: https://github.com/ToadKing/dpi-bug

To reproduce, you must have multiple monitors on Windows with different DPI levels. The primary monitor on your desktop should be a high DPI one, while a secondary monitor should be lower DPI.

### Screenshots
High DPI primary monitor:

Lower DPI secondary monitor (stretches off the monitor):

### Additional Information
The behavior works in 6.0.5, but is broken in 6.0.6. Might be #19928/#20001 or the Chromium upgrade?
