When using an SVG font in HTML, if the SVG font doesn't contain a glyph that is in the text, font substitution doesn't work. The glyph defined by <missing-glyph /> is rendered instead of an alternate from another font that does define the glyph.
This is using WebKit nightly build 30662.

Slightly modified testcase
To make the testcase work in Opera as well, make it a XHTML document.
The bug seems gone in trunk though, I'll create a testcase for the use within DRT soon.
Fixed in r89233.
