hunboy has just created a new issue for 

== support position:sticky inside an overflow:hidden|auto on general 
parents ==
css3 position

Currently the position:sticky element exclusively works when the all 
of general parents are overflow:visible. This is problematic a little 
whilst we use overflow:hidden trick for clearfix etc.

Testcase attached. Here is a simplesample, how is the layout broken 
when we change the overflow to visible, however sticky starts to work 
in that case. I detected, all of general parent-elements in the 
parent-path must be overflow: visible, which is weird a little. Any 
overflow:hidden in the parent-path kills the sticky.

ER: sync somehow the spec to allow sticky subcontainers inside a 
overflow:hidden general parent.
