Heatmap animation is flickering

This notebook was posted almost two years ago. At that time the transition was smooth, like in this gif created from the animation generated in notebook.


Today I updated the notebook here setting visible=False in axes definition, and increasing the frame duration, but the transition isn’t smoother and the animation is still flickering.
What was changed in the last ploty.js/ versions that led to this odd animation?
