Sample

Chrome Version       : 16.0.912.36
OS Version: Goobuntu
URLs (if applicable) :
Other browsers tested:
  Add OK or FAIL after other browsers where you have tested this issue:
 Chrome MacOS: FAIL
     Safari 5: SVG filters not available
    Firefox 8: OK

What steps will reproduce the problem?
Create an animated SVG element and a filter over it.

What is the expected result?
The element's movement and size should not be affected by the filter.

What happens instead?
The element annoyingly jumps around and stretches by a small amount.

The attached file has some text under animated filters (in red and green), where the x, y, width or height attributes of the filter change. None of these should have any effect on the positioning of the text, but the text jumps about quite a lot. The last column of the example has only the text moving, and the filter still causes it to jump badly. 

The top line on the right shows the text moving without a filter, where the problem is not present.
