Dragging seekbar resets advanced javascript movement

Hello,

In one of my projects, I created a moving bar for points calculation, using the native Advanced Javascript object.x += 3 (example) for every point actualization. The problem is, when you use the seekbar to move on the timeline (I use it for the purpose of optional voiceover), the position gets resetted. Which, as you can guess, is highly unwanted. Is there a way to make it "stick" to the place even while moving the seekbar? I get that it will move if there was addtotimline javascript, but that's simple "on click", which shouldn't be connect to the timeline, right?

I even created a very simple mockup, just click the arrow, the rectangle will move, and then drag a seekbar. The rectangle position will reset.
