Steps to reproduce the problem:
1. Open any image in new tab. For example: http://storage4.static.itmages.ru/i/15/0813/h_1439484083_6926813_7d26acc17a.jpg
2. Press Ctrl+A

The image should be highlighted in a blue background:

And Firefox: http://jpegshare.net/14/64/1464b0eac3ade67109db9ac2560c6b07.png.html

What went wrong?
The image is not highlighted in any way, but it is selected.
Press Ctrl+A and drag the image: http://jpegshare.net/d0/8c/d08c1ac38006b3c55a073c099257cbe1.png.html
Drag the image without pressing Ctrl+A: http://jpegshare.net/ba/a0/baa02a1c9c17ce6e2b1c0ed2f1afefa1.png.html
