1635517 - Filter out certain nodes in native mac accessibility tree

Status: RESOLVED FIXED

(Core :: Disability Access APIs, defect, P1)

Description

[Eitan Isaacson [:eeejay]]

There are some gecko accessible types that don't have an equivalent mac accessible type, and need to be skipped. For example optgroup elements don't have a mac equivalent and need to be skipped. Their children should be added to the skipped gecko accessible's parent, and the parent-child linkage should be mutual.

We also need to make sure we don't "leak" skipped accessibles to the platform, for example a skipped accessible should not return from a hittest, should not be present in other attributes, and a11y notifications should not be posted on its behalf.
