This doesn't make sense. How does being camel case have any impact on if you
match the star? 

[rune, 2015/04/22 21:48:24]

starAtom is not added to the bloom filter for any elements, so selectors with
starAtom should not cause rejection. <foreignobject> should match foreignObject
type selector, so foreignObject selectors should not be rejected if
foreignobject is pushed into the filter. As the description says, the
alternative is to push both foreignobject and foreignObject for <foreignobject>,
which would add complexity to the push part instead.
