Feedback for slide builds are not emitted and even on polling never reach 0 when going backwards

[rse]

I've a teleprompter application which optionally controls PowerPoint through OSCPoint. When I scroll forward and a slide has builds, I can progress through the builds and receive the correct feedbacks. The feedback for the current build position starts at 0 BEFORE the first click-based animation and then goes from 1 to N where N is the number of click-based animations (aka builds). But when I go backward in the teleprompter, the reverse operations should be done. Here, first, we have the bug that OSCPoint does not emit feedbacks at all. But when I request the feedback in a busy polling way through the "refresh" action, the builds once again go from N to 1 but then it stays at 1 and never goes to 0 again, even if PowerPoint already reached the visual state BEFORE the first click-based animation. So, there are two bugs in OSCPoint: it does not emit feedbacks for builds when going backwards and its "/oscpoint/slideshow/builds/position" feedback never reaches the original build of 0 again.
