I believe https://bugs.webkit.org/show_bug.cgi?id=91237 is the bug
you're looking for.

I've CC'd relevant chrome folks.

As Maciej notes, webkit-dev isn't really the place for bug reports. :)
 It's a mailing list of over 2000 people.  Most of whom don't care
about specific SVG bugs.

Regardless, thanks for the report.  Please take further discussion to
the bugs system.
