[Windmill-dev] Issue with click command and preventDefault

[Adam Christian]

This is an interesting issue indeed. I am going to investigate! worst  
case scenario has you writing an extension, or a modification to the  
click method on windmill. Hopefully we can find some logic to make  
this work ootb.

thanks for the discovery, the web has so many edge cases!
