3.
Actual Results:
font size starts small and becomes bigger and bigger after a few lines.

font size starts small and should stay like that. other browsers like ns 4.76,
ie5 and ie6 produce the expected results.

"<big@boss.com>"
That's inside the <pre>. That is parsed (correctly, I must add) as <big
@boss.com> which is the start of a <big> tag, so the text gets bigger....
You really want to escape HTML-tag-stuff before sticking it inside <pre>.

mozilla interpretes e.g <big@blabla.com> or <a_virus@rolandberger.com> as a
html tag. Both are email addresses. I think the parser should trigger more
precisely to know tags than to tags which may start like known ones. In the
example above <big> is a known tag but mozilla triggers already to <big.

> Both are email addresses
Which means nothing to the HTML parser....
'@' is not an allowed char in a tagname, so <big@> and <big @> are equivalent.

I don't see how this could be implemented (checking to see if something is a tag
or an angle-bracket-enclosed E-Mail address) without standing a strong risk of
breaking other documents.
However, the HTML standard (I checked 3.2 and 4.01) states that a <big> tag
can't appear within a <pre> tag. See
http://www.w3.org/TR/html4/struct/text.html#edef-PRE
Therefore, it *is* a problem that the text is getting bigger.
Other tags that shouldn't be parsed inside of a <pre> tag are img, object,
small, sub, and sup in 4.01. In 3.2, the additional tags are img, small, sub,
sup, and font.
Severity: normal → minor
Status: UNCONFIRMED → NEW
Ever confirmed: true
Summary: text in <pre> tags become bigger and bigger instead of being displayed in same size → <big> should not be parsed inside of <pre>

We now allow '@' in tagnames, so original testcase works. This is a testcase
for the general issue of <big> in <pre>.

IE6 most certainly allows <big> and company inside <pre>, so we're not going to
be enforcing this part of HTML, just like we don't enforce so many other
containment rules...
Marking wontfix.
