Color picker not showing up

[vibber]

When including an HTML5 color picker the actual color picker window does not show up.
Like this:
A colored square is displayed but no color picker popup window show.

Tested on Mac OSX 10.8.3

Still occurs on v0.5.1-x64 (Ubuntu 13.04)

To reproduce this bug, just go to

and try to open the color picker
