RangeError: Maximum call stack size exceeded when using timezone-mock

[Zeikko]

I'm using timezone-mock to test that our time formatting works correctly in different timezones.

This worked fine with date-fns/tz 1.1.2 but when upgrading to 1.2.0 I get RangeError: Maximum call stack size exceeded error with the following stack trace:

RangeError: Maximum call stack size exceeded

...

The minimum reproduction steps are:

import timezoneMock from 'timezone-mock'
import { format } from 'date-fns'
import { tz } from '@date-fns/tz'

timezoneMock.register('US/Pacific')
format('2020-01-01T15:30:00+02:00', 'H.mm', { in: tz('Europe/Helsinki') })

Package versions used:

@date-fns/tz: 1.2.0
date-fns: 4.1.0
timezone-mock: 1.3.4

I'm not sure if I should file the issue in date-fns/tz or timezone-mock but I'll start from here since the update of date-fns/tz caused the issue for me.
