I mean if you use a 255/255 alpha shape as in you reduced test case, then sure the feColorMatrix of 1 works.  But if you're trying to create a drop shadow from opacity 1/255 then you have to scale up the value by 255.  That doesn't overflow in Chrome/Firefox, but appears to in WebKit.  Is there any suggested workaround? The rdar tickets are opaque to anyone but Apple.
