Animation comparison: blink vs webkit

By "filter box" I mean the box of the svg filter (using x/y/width/height attributes)
And by "content box" I mean the box of the element with the filter applied via CSS.

Here's an example where I made the filter box around 2x in scale:

I suspect this will happen with any SMIL animation in a filter where the filter size exceeds the size of the content, but I haven't confirmed that so that should be tested if anyone is interested.
