[16.12] Items popping forward out of circuit controlled belt

Items are "popping" forward creating unintentional spaces when blocked then released by a circuit controlled belt. Here's a blueprint demonstrating the bug (you just need to have as full belt coming in and draining out). Gaps are intentionally made, but the first couple of plates through the "gate" bounce forward just a little. The lanes may even become uneven.

I'm having trouble recreating the bug. There may be some user error on my part.

Captured the popping, I think it depends on the state that the items are in before the system is fully initialized. I apologize for the not so great gif quality.

I can't see it in the gif and was not able to produce something myself with the BP.

I was able to reproduce this issue but little manually - blue belt fully compressed:
1/ remove one segment of blue belt (to make gap)
2/ place again blue belt (so items go on it)
3/ remove same segment again (so you have about 2~3 long chunk of items ahead)
4/ place again blue belt
Step 4 makes first item on one lane (or both) to jump one "belt increment" ahead.qww
It is visible on this gif if you know what to look for - first items after gap are little ahead. This jump looks related to belt optimisation - with "show transport-lines" this jumping forward occurs where lanes conect to next lanes with red arrows, when they dissapear after 1 second, there is no problem.

I also ran into this, even without circuit controlled belts. There are two jumps, one furnace width to the left of the player, and one furnace width to the right. Save attached.

Much better gif, thanks!
It's a small bump, but it's there. IIRC, an item takes up 9 (?) positions on a belt, it seems that items are jumping forward a position.
@DaveMcW
What software are you using to capture the gif? How are you keeping the speed consistent, did you somehow turn down the fps of the game for capture?

I am a control freak, so I take a bunch of screenshots and use FFmpeg to compile it into a movie.
