no calendar on partial bundles

[mattcorner]

I am trying to get the connectgaps property to work in a React app where I use a custom plotly.js bundle to reduce the build size.

With this custom bundle which imports only Surface, connectgaps does not work.

If I use the full plotly.js bundle, the plot works properly.

See attached github repo for a simple reproduction showing the two plots side-by-side.

I presume that I either need to import something extra in the custom bundle, or that lib/Surface is missing a dependency?

Thanks for reporting. Here is a codepen illustrating the bug.
That's possibly related to surface trace using a function from heatmap trace.

@alexcjohnson strangely there is no calendar attached to axes when using partial gl3d bundle: demo.

Not only gl3d but also other partial bundles e.g. gl2d & basic are also impacted by this bug: demo.

To clarify how calendar issue is linked to surface.connectgaps issue,
calendar is undefined here when using partial bundle:

plotly.js/src/traces/surface/convert.js

rawCoords[2][j][k] = this.getZat(j, k, data.zcalendar, sceneLayout.zaxis);
