Research direction

Start by reproducing the contour or heatmap animation described in the linked community discussion and determine whether the failure is in plotly.py or JavaScript. Trace the animation path to identify the responsible component. Done means contour and heatmap traces remain visible throughout animations, with the relevant behavior verified by a regression test if the project has one.
