295652 - [FIXr]document.open("text/html; charset=..") opens as text/plain

Status: RESOLVED FIXED

(Core :: DOM: Core & HTML, defect, P1)

Description

[Udo Richter]

Documents opened with document.open("text/html; charset=iso-8859-1") display its
content as text/plain with visible html tags. Although this is not a valid mime
type, displaying it as text/plain is a bad idea, because this is a common
mistake, and IE displays it as text/html.

On a side note: Clicking reload on a generated page turns the page into
text/html, and tags disappear.

This was introduced by the checkin of bug 73409

The current behaviour is to treat everything but text/html as text/plain. I'd
suggest accepting at least everything that begins with text/html.

Requesting approval for 1.8b3.	This is quite safe, and gives us better compat
with IE and NS4.
