Build ID: 20150122214805

Steps to reproduce:

1. Go to: http://en.wikipedia.org/wiki/Test_%28assessment%29
2. Highlight "Test (assessment)"
3. While the text is highlighted and you haven't released the cursor, move the cursor all the way up up off the screen then move the cursor back down to the text you highlighted.

This issue happens on most Wikipedia pages and I've seen it happen on some other websites. (Can't give specific names right now, sorry)



Actual results:

Everything is highlighted except the original text you highlighted.


Expected results:

Everything will no longer be highlighted except the original text you highlighted.
Summary: Highlighting text and moving cursor all the way up off screen causes everything to be selected on certain websites → Highlighting text and moving cursor all the way up off screen then back over the highlighted text causes everything except the text you highlighted to be selected on certain websites
