• Status: NEW
• Component: Forms

I Steps:
1. Go to http://supportforums.blackberry.com/rim/board/message?
board.id=feedback_ideas&thread.id=496
2. Create a reply
3. Click Insert Code
4. Type or paste text with newlines
5. Press Insert
6. Press Submit

II Issue:
When Insert is pressed, the text is put correctly into the body of the 
message via javascript but when submit is pressed, it appears that the 
newlines are stripped as evidenced by the lack of newlines in the resulting 
message. 

III Other Browsers:
IE7: ok
FF3: ok

IV Nightly tested: 40471

Bug in Chromium : http://code.google.com/p/chromium/issues/detail?id=2007

It looks like in the LayoutTests/fast/forms/textarea-crlf.html that is the expected behavior. I'm not sure why or if there is a spec that says it should be that way.

Based on the test, it looks like it's stripping the carriage return as soon as the value is assigned in the dom. Also when innerHTML is assigned the same result happens.

Tested on Nightly 47686.

I am unable to reproduce this based on steps mentioned in Comment 0 but I looked in Chrome bug and found that it was fixed in this commit:

Link - https://chromium.googlesource.com/chromium/src.git/+/e26eb3267527f0d5633283cef06a13995e0d41eb

From above commit, I took test cases:

Test Case 1 - https://jsfiddle.net/3s2u8xaz/show

I get following in all browsers:

*** Safari 15.6 on macOS 12.5 ***

FAILED: expected "hello
world

webkit" but got "hello
world
webkit"

*** Firefox Nightly 105 ***

FAILED: expected "hello
world

webkit" but got "hello
world
webkit"

*** Chrome Canary 106 ***

PASS

I think I botched on test case 2 and 3 but I just copied the scripts from Chrome test case.

Just wanted to share update on this bug. Since on Test Case 1 - Safari do give different result compared to Chrome, I am going to change status to "New".
