Second screen mouse pointer offset in extensions on mixed dpi setups

Reported by philippe...@gmail.com, Mar 22 2017

Issue description

UserAgent: Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Safari/537.36

Steps to reproduce the problem:
1. Install an Extension (e.g. Adblock Plus or Ghostery)
2. Have two monitors attached to your system NOT sharing the same Scaling level (e.g 150% on the primary, 100% on the secondary screen; for more details see https://www.thurrott.com/windows/windows-10/4597/windows-10-feature-focus-display-scaling)
3. On the secondary screen try to use the extension.

What is the expected behavior?
Mouse clicks and hovers happen where the cursor is.

What went wrong?
Mouse clicks and hovers happen not where the cursor is but some place else.
See print screen attached:
While the cursor hovers over "Enabled on this site" the extensions assumes the mouse to be over "Ads blocked" (visualized by the darker background).
Clicking with the current cursor position opens the "Ads blocked" menu and doesn't enable/disable ad filtering.

Did this work before? N/A
