Error if custom function IDs are the same ignoring periods and underscore

[parched]

Bug Report

• Host: Excel
• OS: Windows
• Browser: (fill out if relevant/applicable)
• Environment: (fill out. eg: alpha, beta, prod)

Expected behavior:

I expect to be able to create two functions that have different IDs ignore case.

Actual behavior:

Steps to Reproduce:

/**
 * Calculates the volume of a sphere.
 * @customfunction SPHERE_VOL
 * @param {number} radius
 * @returns The volume of the sphere.
 */
function sphereVolume(radius) {
  return (Math.pow(radius, 3) * 4 * Math.PI) / 3;
}

/**
 * Calculates the volume of a sphere.
 * @customfunction SPHERE.VOL
 * @param {number} radius
 * @returns The volume of the sphere.
 */
function sphereVolume2(radius) {
  return (Math.pow(radius, 3) * 4 * Math.PI) / 3;
}

Screenshot:

This is what it looks like after that error.
It says they have been registered correctly, but clearly have not.

Hi @parched, thanks for submitting this issue.

@jiju-MS Can you take a look at this custom functions issue in the Script Lab repository?
