Related notes:

I would think that the definition of 'presented region' should not account for the semantics of itts:forcedDisplay since the document should be conformant regardless of the value of 'displayForcedOnlyMode'.

It's already included indirectly because itts:forcedDisplay effectively overrides the value of tts:visibility and tts:visibility is included in the definition of "presented region".

What is not clear is if the computed value of tts:visibility that applies to "presented region" is pre- or post- the itts:forcedDisplay override.
