When using the keyboard to select a new option in a select element, and afterwards shift selecting additional elements. The the selection that you jumped from with the keyboard shortcut is reselected.

I have only been able to reproduce this issue in webkit browsers
Affected browsers: Google Chrome 37, Chromium 37, Safari 7.1

Steps to reproduce:
1. Create html document containing a <select multiple size=10> element with 10 options (eg. a - i), or go to http://jsbin.com/satezijosoze/1/
2. Select option with mouse (eg. c)
   Selection is now [c]
3. Press keyboard key to jump to another option (eg. h)
   Selection is now [h]
4. Hold shift and select another option (eg. shift + arrow down)
5. Observe: selection is [c,h,i]
6. Expected selection was [h,i]
