Steps to reproduce:
1. Open the attached test case in Firefox.
2. Use Accerciser to view the accessibility tree.

Expected result: There would be no objects with ROLE_UNKNOWN.

Actual result: Both of the examples with the semantics element have an accessible object with ROLE_UNKNOWN as the child of the ROLE_MATH element.
Summary: Do not expose MathML semantics element in the accessibility tree for ATK → Do not expose MathML semantics element in the accessibility tree

summary of the discussion: neither semantics nor annotation elements have a presentation or provide a special value for assistive technology. If the browser reveals them via UI for all users then the assistive technology users are supposed to use on that UI.

that seems to be safe but would be really nicer to not have gaps in numbering (there's no much of items underneath of this one)
