1686839 - textbox children get partially pruned

Status: RESOLVED FIXED

(Core :: Disability Access APIs, defect, P2)

Description

[Eitan Isaacson [:eeejay]]

STR:

1. Load data:text/html,<div id="textbox" role="textbox">Hello <a href="#">strange</a> world</div>
2. Dump accessibility tree

Result:
textbox has two children, an AXLink (strange) and a AXStaticText (world), the first text leaf is missing.

Expected:
textbox should ave three children a text leaf, link and another text leaf.

I think that perhaps the other children are not in the initial tree, so at creation time the textbox only has one child so MustPrune returns true which makes us skip the first child.

Another way to reproduce this is to add children to widgets after they are created. The MustPrune rule will only work on the first child.
