test case

Steps to reproduce:

1. Open the attached test case in Epiphany.

2. Using Accerciser, attempt to set the caret position within the paragraph and within the first list item, by:

A. Selecting the corresponding object in Accerciser's tree of accessible objects

B. Typing 'acc.queryText().setCaretOffset(n) - where 'n' is the desired offset.

Expected results: You'd be able to set the caret offset for both objects.

Actual results: You can set the caret offset for only the paragraph; not the list item.

Related aside: In both cases, True is returned suggesting that the offset was successfully positioned. I shall open a separate bug requesting a more accurate return value.

Impact: Orca has 'structural navigation' commands which include the ability to navigate amongst HTML elements ('p' for paragraphs, 't' for tables, 'l' for lists, etc.). A typical use case is to locate a desired section of the page via structural navigation and then use caret navigation to read or select the text in that section. Because we cannot set the caret within a list item, this navigation/selection technique fails for lists and their items.
