document.open should reset the DocType to BackCompat (quirks mode) to match IE

As part of fixing:
https://bugs.webkit.org/show_bug.cgi?id=24336
for WebKit, I discovered that Gecko does not match IE and WebKit by resetting the DocType BackCompat after a document.open.

See attached test case.

Reproducible: Always

When running the test case with a recent (2.0b3pre (1.9.0.8pre 2009031706)) nightly Camino build under PPC Mac 10.4.11, the first two tests "PASS", and the last three tests "FAIL", FWIW.

Actually, after further testing, I'm not sure document.open() clears the document at all (as it does in IE and WebKit)

That's bug 325352.

Move all DOM bugs that haven’t been updated in more than 3 years and has no one currently assigned to P5.

Invalid per current document.open spec. In fact, we now want to reset it back to standards mode. See bug 1489308 comment 0 third bullet point.
