591988 - Empty first line in text area disappears

Status: RESOLVED DUPLICATE of bug 620267

(Core :: DOM: HTML Parser, defect)

Description

[Erwin Wessels]

User-Agent:       Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0b4) Gecko/20100818 Firefox/4.0b4
Build Identifier: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0b4) Gecko/20100818 Firefox/4.0b4

Whenever I open a page with a textarea whose contents start with one or more blank lines, those lines disappear (i.e. the textarea immediately skips to the content.)

This doesn't happen if there are spaces or tabs involved - just newlines.


Reproducible: Always

Steps to Reproduce:
1. Open a document with a textarea, which starts with a new line, like such:
<textarea>

This should be line number 2
This should be line number 3</textarea>
Actual Results:  
'This should be line number 2' shows up as the 1st line.

Expected Results:  
There's a blank line inside the textarea, before 'This should be line number 2'.

View source shows it's there, view generated source doesn't.

Attachment: test handling of leading newlines

Component: for this bug should be HTML: Parser

with html5.enable=true
PRE and TEXTAREA elements are discarding all leading newlines

similar bug has google chrome 10, which keeps newlines in textContent but discards one newline in value of textarea
