Bug 6200 fixed the PHP parser's handling of <blockquote>, which is now treated that same as <div> with respect to preformatted contents.
However, we are currently failing the "Bug 6200: Preformatted in <blockquote>" parser test:
<blockquote>
Foo
</blockquote>
The 'Foo' is not correctly wrapped in a <pre> by parsoid.
Version: unspecified
Severity: normal
