#1988 ScriptException: TypeError: Cannot find function resolvedOptions in object [object DateTimeFormat]

[Franco Qualcuno]

Hi guys, thanks for your excellent work. I found an issue with javascript in a web page that until yesterday (2018.09.07) works correctly.

I attached the simple code that doesn't work anymore.

This is the exception thrown:

Thanks

The error seems throwed by javascript code

Intl.DateTimeFormat().resolvedOptions().timeZone
