Bug 115873

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
