344392 - Prefer markup over frame type for determining HTML accessibles

Status: RESOLVED FIXED

(Core :: Disability Access APIs, defect)

Description

[Aaron Leventhal]

Currently the frame type always gets the first chance to say if and what kind of accessible should be created, via nsIFrame::GetAccessible()

After that we call CreateHTMLAccessibleByMarkup() to catch specialized cases based on the markup.

We're doing this in the wrong order. The problem shows up under newatk where things like nsHyperTextAccessible get created for an <option>, because they use nsBlockFrame.

Attachment: First check for role=presentation, then check for accessible by markup type, then check for accessible by frame type (if HTML), finally check to see if generic accessible needed
