Description
I cant manage to get the heat map to show up in any react project, try the following:
- clone the react "plotly.js-demo-app" from the original remote
- search in the top right: "Heatmap" and try any option
- you will see that it can show the values when hovering with the mouse but would not show the colors themselves.
This is what shows:

This is what shows in in the original website of the demo, here

Research direction
Reproduce the issue by cloning the react "plotly.js-demo-app" and selecting a Heatmap from the top-right search. Compare the local rendering with the linked demo site, then trace the heatmap rendering path to determine why hover values appear without colors. Done means Heatmap colors render visibly in the React demo as they do on the original site.
