Description David Alcala 2013-05-09 14:00:09 PDT 
Transformed content in named flows using 2D transform that overflows region box is clipped.  I couldn't find anything in the spec that says the source content that is transformed should be clipped.  By default, the overflow content should show.

Reproduction steps:
Open the attached file scaleY-webkit-bug-region-clipping2.html in a browser that supports regions (Chrome Canary or WebKit Nightly) on Windows or Mac.

Actual Results:
You see a 100px x 100px green square.  The bottom half of the green rectangle is getting clipped by the region div. 

Expected Results:
You should see a 100px x 200px green rectangle – the source content that overflows the region is not clipped by the region.  See scaleY-webkit-bug-region-clipping2-no-region.html for how it should look. Or, if you remove the transform (scaleY-webkit-bug-region-clipping2-no-transform.html), you can see that the source content that overflows the region also is not clipped by the region.

Workaround:
None
