406595 - a11y hierarchy completely broken (everything below app frame is gone) on all platforms, effective Dec 3

Status: VERIFIED FIXED

(Core :: Disability Access APIs, defect)

Description

[Marco Zehe (:MarcoZ)]

With the Dec 3 build, all accessibility information is completely gone once a document is loaded. Everything below the App frame node has disappeared.

This appears to be a regression of bug 406168, which was the only a11y change submitted on Dec 2.
