Vue.js version

1.0.16

I am referring to #2185 and #2169 because upgrading from 1.0.15 to 1.0.16 broke my drag and drop.

According to http://www.w3schools.com/tags/att_global_draggable.asp
"true" is a valid value for the attribute "draggable".

Steps to reproduce

I was using
<div :draggable="isDraggable"></div>
which was working fine until the changes and rendered to <div draggable="true"></div>

<div :draggable.boolean="isDraggable"></div>
renders to <div draggable></div> which is wrong and not working.

Workaround

<div :draggable="isDraggable && 'true'"></div>
renders to <div draggable="true"></div>

You can close this issue with "works as designed",
but i wanted to leave at least the workaround in the issues.
