Test 0120 (Media Overlays Reflowable Tests): mo-audio-030 Wording

[pettarin]

Current:

If playback immediately continues to the next section after the preceding sentence is announced in full, the test passes.

Proposed:

If playback immediately continues to this sentence after the preceding sentence is announced in full, the test passes.

Rationale: this test should check whether the Reading System correctly computes the length of clip_times_tests3A.mp3, disregarding the clipEnd="00:00:20.000" in the associated SMIL file. However, the MO playback does not end with mo-5-b (the second-to-last paragraph, associated to clip_times_tests3A.mp3), but with mo-9-b (the last paragraph, as quoted above). Hence, after computing the correct clipEnd for mo-5-b, the Reading System should not jump to the next XHTML, but it should render (immediately) the last sentence instead.
