114759 - <textarea> lowercases things that look like html closing tags

Status: RESOLVED DUPLICATE of bug 64799

(Core :: Layout: Form Controls, defect)

Description

[Craeg Strong]

I use <textarea> to edit XML files, and some of the tags look like HTML tags.
For example we might have:
<Section>
<Title>intro</Title>
<P>
  this is a test
</P>
<P>
  here's paragraph two
</P>
</Section>
As you will probably see from the above (this is being entered in a textarea)
The closing "P" tag and the closing "Title" tag are lowercased.  HOWEVER,
the opening tags are NOT lowercased.  Neither Opera nor Internet Explorer 6
exhibit this behavior.  According to spec, the content should be left alone.
Apparently, the textarea layout algorithm is being too clever and lowercasing
anything that it sees as an "html" closing tag.  Curious.

Um... The text you submitted does not have the tags lowercased...

Are you pre-filling the textarea with XML and not escaping the "<" and ">"
characters?
