Steps to reproduce the problem:
1. Open Chrome on a retina display, I used a MacBook Pro (Retina, 13 inch, Early 2015).
2. Open the attached HTML or go to http://jsfiddle.net/Luxkmpjv/
3. Scroll down the page so that the text hides behind the sticky header.
4. Hover over the text behind the sticky header.

What is the expected behavior?
The cursor should not change and it should not be possible to select text.
The sticky header should catch all the mouse events, as it is rendered in front of the text.

What went wrong?
 The cursor changes to a text-selection cursor (it's not visible in the GIF), and it is possible to select text.
Generally, all mouse events seem to go through the sticky div instead of being handled by it.

Did this work before? N/A 

Does this work in other browsers? Yes
