Error: Undefined symbol x

[Evan-CTL]

Now that sentry is connected to 3Demos it’s throwing errors that used to be overlooked. In this case there is a mathJS error caught in Function.svelte. The example before uses the parameters from this link: https://comic.ctl.columbia.edu/?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

It’s not easy to trace the cause in production due to the bundling, but running locally I managed to pin it down to the following:

media/src/objects/Function.svelte → updateBoxes() → math.evaluate(c)

The x variable in the formula string is not recognized. This error might be triggered by other objects, but this is the source of the error in the URL above.
Notably: This bug does not seem to hinder the loading or use of the web page.

The integration feature is not built to hande non-constant bounds. I'll do a check for this to fix it, but the whole feature should be moved to a Story anyway and needn't be attach to every instance of a function graph.
