Click event handled on Dijits in disabled state

[dylan]

As reported by Bjoern Burger:

1. Put a dijit/form/Button on a simple html page
2. Use a onClick handler, which:
   1. Set disabled=true
   2. Run javascript code
   3. Set disabled=false
3. First click on button
4. Button is now disabled
5. Click again on this disabled button
6. Check your console > the onClick handler runs twice!
