356369 - GetTextAtOffset gets wrong characters amount

Status: RESOLVED DUPLICATE of bug 348901

(Core :: Disability Access APIs, defect)

Description

[Mike Gao]

1. Reference the above URL for the testcase.
2. Use word start or word end
3. check on "Track mouse clicks"
4. use "Character", "Word start", "Word end", "Line start" or "Line end"
5. click on 
"abc
123"

We can see the amount of characters according to the offset is not right.

I found there is one whitespace before "abc" and one whitespace after "123" while debugging.

Comment 2

<span>
abc<br>
123
</span>

The "cr" in HTML source introduced a space in AccessibleHyperText.
So it's (I use $ for space, # for \000A)

$abc#
$123$

In case of Character, we get:

Text:  a [0,2] b [2,3] c [3,4] [4,5] 1 [5,7] 2 [7,8] 3 [8,9] [9,10]

[0,2] is "\na", [5,7] is "\n1" and [9,10] is "\n" at first, but "\n"s are replaced by " " in nsHyperTextAccessible::GetPosAndText().

I think this is a duplicate of bug 348901. Is it?
