Start by reproducing the issue in Google Chrome on macOS during an animation, focusing on the pointerover interaction and the data it returns. The issue provides no reproduction link, steps, named files, or tests, so identify the relevant animation and pointerover entry points first. Done means pointerover reliably provides the expected data while animation is running, with a regression test if the project’s existing test structure supports it.
