755682 - Don't return from document.open() early if the insertion point is undefined

Status: RESOLVED WORKSFORME

(Core :: DOM: Core & HTML, defect, P3)

Description

[Henri Sivonen (:hsivonen)]

The spec says "If the document has an active parser that isn't a script-created parser, and the insertion point associated with that parser's input stream is not undefined (that is, it does point to somewhere in the input stream), then the method does nothing. Abort these steps and return the Document object on which the method was invoked." but our document.open() implementation doesn't check the "the insertion point associated with that parser's input stream is not undefined" part.

In what case is this observable?

I don't recall. Just now, I tried:

Foo
<script>
    document.open();
</script>

and it looked like document.open correctly did not take effect.
