Drop-shadow filter does not work when 'overflow' property is set to 'hidden'

Reported by insensi...@gmail.com, Aug 18 2016

Issue description

Chrome Version       : 52.0.2743.116 (Official Build) m (32-bit)
URLs (if applicable) : https://jsfiddle.net/6baweyro/8/
Other browsers tested: Firefox/Microsoft edge
  Add OK or FAIL, along with the version, after other browsers where you
have tested this issue:
     Safari:
    Firefox: OK
         IE: OK

What steps will reproduce the problem?
(1) Open https://jsfiddle.net/6baweyro/8/

What is the expected result?
All three boxes on the page should have shadow, even if element 'overflow' property is set to 'hidden'

What happens instead?
Middle box having 'overflow' property set to 'hidden' does not have shadow

I tested the same page in latest Firefox/Microsoft Edge - all three boxes have shadow in these browsers. I am not sure what says W3C filter specification about this.

I think this falls on the paint side of things. If not please sent it back my way.

Thanks for taking the time to file this, I do think it's a bug.

box-shadow uses filters internally so I'm not sure why we're applying the clip early in the filter cases but not the box-shadow one. Possibly due to how ComputedStyle::hasBoxDecorationBackground() works?

Testcase: http://jsbin.com/rotuhi
I just updated jsfiddle example, removed -webkit prefix since Chrome 53 is released https://jsfiddle.net/6baweyro/9/ allows unprefixed filters. This issue has priority 2 "want (for current milestone)" and labeled "M-53" Chrome 53 is released and I am not familar with Chrome release cycle, so I wonder is there an approximate release I can expect this issue to be fixed? 

Many thanks.
This issue seems to be already fixed. I am unable to reproduce it in Chrome 60.

Fixed no doubt by the refactoring we have done.
