test case

+++ This bug was initially created as a clone of Bug #73431 +++

Steps to reproduce:

1. View the attached test case in Epiphany
2. Resize the window so that the text wraps
3. Enable caret browsing
4. Launch the attached test script in a terminal
5. Arrow Up and Down amongst the lines of text

Expected results: The test script would always print the correct text for the current line.

Actual results: The test script fails to present the correct text for the second list item.

Another test case

An additional get_text_at_offset() failure/test case. (Not sure if it's a variant of the same bug or a different bug.)

Thanks for the patch. It looks good to me with the exception of the missing comments in the ChangeLog.

You should still ask for an official review, though

> +        (textForRenderer):

A brief description of the change for textForRenderer would be nice here.

> Source/WebCore/accessibility/gtk/WebKitAccessibleInterfaceText.cpp:82
> +            if (object->isReplaced() && !object->isListMarker())

Oh! It indeed looks like a mistake in the code (and not coherent withthe comment).

Good catch (/me runs and hides)

> Source/WebKit/gtk/ChangeLog:11
> +        (testWebkitAtkGetTextAtOffsetWithSpecialCharacters):

Something like "Updated unit test" would be nice here

Thanks for the review! :) Perhaps I should have coffee first and then respond, but.... What missing comments?

Looking at: https://bugs.webkit.org/attachment.cgi?id=158452&action=prettypatch, I see:

    Source/WebCore/ChangeLog
    8        Be sure the list item marker to be ignored is actually a list item marker prior to ignoring it.

    Source/WebKit/gtk/ChangeLog
    8        Include a paragraph in a list item when testing atk_text_get_text_at_offset().

Adding Chris to CC for review. (It's a one-line bug fix.)

Looks like I should be the one drinking coffee first :-). I meant the missing  comments _per-function_, but it's true that in this case it maybe makes not much sense since it would be duplicating the stuff in the general description.

Anyway, in my defense I must say I should not be here today as it's a bank day and so I'm officially not working :).

i think this comment is a little hard to follow

Maybe something like "Fix a logic error when checking if an object is a list marker"

Agreed "Updated unit test to include a paragraph in a list ..."
