Description

The new image trace seems to have a flashing/jumping behavior when zoomed in and panning on Firefox and Safari. (Firefox version 69.0, Safari version 13.0.3)

Example from https://plot.ly/python/imshow/

image_jump

This jumping does not happen on Chrome but I do see it on Firefox/Safari. Not sure if it's related, but in all three browsers, the tooltip also seems to jump to another location when the pan is completed.

Research direction

Start by reproducing the image-trace behavior at https://plot.ly/python/imshow/ in Firefox 69 and Safari 13.0.3 while zooming and panning, then compare it with Chrome and observe the tooltip after panning completes. Done means image and heatmap traces remain stable and the tooltip stays at the correct location across the reported browsers.
