SVN commit 873059 by orlovich:

Rework how we do onchange for input/checkboxes, unbreaking it and simplifying things.
As we only want to fire it in response to user events, this just does it in defaultEventHandler.
Fixes kde-look wallaper settings, and along with Germain's previous fix this covers 
#165607, #170451. This also doesn't suffer from #148118
