Description

Problem: Objects sometimes are moved indirectly, e.g. parent position, scrolling or transformation changed

- Quick and dirty (and slow solution) idea: "when in doubt let it tick"... that seems to be the most used solution in the web for this problem

- alternative idea: use a mutation observer that follows yourself and all your parents, this would work, but has the side effect of having to be garbage collected or better, that mutation observer has to be clever and (de-)install itself in parents if any parent changes....

Research direction

The issue does not name a file, test, or entry point. Start by locating the code that tracks object movement and inspect how parent-position changes, scrolling, and transformations are currently handled. A complete change would need a decided detection strategy and tests demonstrating that indirect movement is detected without unnecessary work.
