--- Comment #3 from Simon Fraser (smfr) <simon.fraser at apple.com> ---
There's a retain cycle:

3   0x107903384 WTF::RefPtr<WebCore::SVGFontFaceElement, WTF::DumbPtrTraits<WebCore::SVGFontFaceElement> >::RefPtr(WebCore::SVGFontFaceElement*)
4   0x1078db8ed WTF::RefPtr<WebCore::SVGFontFaceElement, WTF::DumbPtrTraits<WebCore::SVGFontFaceElement> >::RefPtr(WebCore::SVGFontFaceElement*)
5   0x1078db696 WebCore::CSSFontFaceSource::CSSFontFaceSource(WebCore::CSSFontFace&, WTF::String const&, WebCore::CachedFont*, WebCore::SVGFontFaceElement*, WTF::RefPtr<JSC::ArrayBufferView, WTF::DumbPtrTraits<JSC::ArrayBufferView> >&&)
6   0x1078dbb9d WebCore::CSSFontFaceSource::CSSFontFaceSource(WebCore::CSSFontFace&, WTF::String const&, WebCore::CachedFont*, WebCore::SVGFontFaceElement*, WTF::RefPtr<JSC::ArrayBufferView, WTF::DumbPtrTraits<JSC::ArrayBufferView> >&&)
7   0x1078cc4f6 WebCore::CSSFontFace::appendSources(WebCore::CSSFontFace&, WebCore::CSSValueList&, WebCore::Document*, bool)
8   0x1078de81d WebCore::CSSFontSelector::addFontFaceRule(WebCore::StyleRuleFontFace&, bool)
9   0x1078ddd9d WebCore::CSSFontSelector::buildCompleted()


Document -> CSSFontSelector -> CSSFontFaceSource -> SVGFontFaceElement -> Document.
