In ThorVG Web Player, the IntersectionObserver is default. This means current ThorVG Viewer has same condition to reproduce.

However in the viewer, I see it renders well.

Additionally, we don't have debouncing logic in that observer. The issue dotLottie has comes from JavaScript side not WASM. Observer callback seems to have some delays, and gets wrong event order due to the debounce.

ThorVG Web doesn't have it, so I think this is fine here. If you have similar error, could you please share your case?

Can't reproduce it with the latest version.
