Probable cause:

Test has been highly intermittent for a while it seems.

Comment 6 Alexey Proskuryakov 2018-07-17 16:01:17 PDT 
The main problem here is that the SVG is rendered at a wrong size:

+  RenderSVGRoot {svg} at (0,0) size 480x360
-  RenderSVGRoot {svg} at (0,0) size 800x600

Definitely worth figuring out how to reproduce. The test is very basic, so whatever causes this problem may well be breaking other tests too.
