v5->v6 Lipsync Improper Conversion

[Enthalpy]

In v5, frames 74 and 75 of this trial were set to "synchronize with speech." In the v6 editor, this changes to "auto," presumably because "synchronize with speech" was the default of v5. However, in the v6 player, there is no lip sync on those frames, presumably because the last speaker's speech mode was "Do not talk."

Regardless, this is an incorrect conversion.

May be linked to a bug where "if a start-up animation is used on a textless frame in a v5 native trial, and the next frame features dialogue from the same character, the corresponding talk animation for the start-up animation will play on that second frame." Actual conditions may be broader, as this bug report suggests. Demo here, investigation to be made.

Also possibly related, the frame after 140 here. Same bug as in previous comment. I'll split these two up if further investigation reveals that they're separate.
