problems with mapbox density heatmap color

Upon reviewing the demonstration provided on https://plotly.com/javascript/mapbox-density-heatmaps, I have observed an issue with the coloring of the last heat map chart that displays earthquake magnitudes. When a user mouses out too much, the coloring appears to be incorrect. It is unclear whether this is intended behavior or a bug, but it does not appear logical to end users and seems like a bug.

For instance, if a user mouses out too far, numerous yellow areas are displayed, giving the impression that all of these areas have experienced 9-degree earthquakes. As a result, it appears as if nearly the entire earth has experienced a 9-degree earthquake, as shown in the image provided. However, when a user zooms in to examine specific locations, the yellow spots disappear, resulting in an absence of yellow spots. This behavior renders the chart significantly misleading to the end user.

I would like to inquire if you are aware of this issue. Is there a workaround or a setting that can be modified to prevent this from happening when a user mouses out too much?

Same behavior has the previous chart as well, which is type of densitymapbox:

However even if mouse in the colors are not right:

These 2 points above have very different values. One is 7 the other is 5.5. According to legend scale we should see different colors

But they are very similar and end user can not see the difference here.

Start with the Mapbox density heatmap demonstration and reproduce the reported behavior while zooming in and out. Compare earthquake magnitude colors in both the density heatmap and densitymapbox examples, including the reported values 7 and 5.5. Done means the visualization communicates magnitude differences consistently across zoom levels or documents a confirmed workaround.
