Description Farley Reynolds 2020-06-16 05:11:23 PDT 
If a variable is declared at the global level with the "let" keyword, functions in other files cannot access it.

If the declaration is changed to use the "var" keyword, the other files are able to access it.

This issue seems to arise when a JavaScript module calls the function that requires the global variable.

I was able to confirm that no other browsers display the issue with the "let" keyword.
