CustomParseFormat does't use a timezone

[tenorok]

Describe the bug

When using input format as array then output format does't take specified timezone.

import dayjs from 'dayjs';
import utc from 'dayjs/plugin/utc';
import customParseFormat from 'dayjs/plugin/customParseFormat';
import timezone from 'dayjs/plugin/timezone';

dayjs.extend(utc);
dayjs.extend(timezone);
dayjs.extend(customParseFormat);
dayjs.tz.setDefault('Europe/Moscow');

// Incorrect, output:
// 31.05.2021 21:00
console.log(
    dayjs
        .tz('01.06.2021 00:00', ['DD.MM.YYYY HH:mm'], 'Europe/Moscow')
        .format('DD.MM.YYYY HH:mm'),
);

Expected behavior

When using just a string for input format the timezone takes correctly.

// Correct, output:
// 01.06.2021 00:00
console.log(
    dayjs
        .tz('01.06.2021 00:00', 'DD.MM.YYYY HH:mm', 'Europe/Moscow')
        .format('DD.MM.YYYY HH:mm'),
);

yes, I met the same problem. Any fix?

I could reproduce the issue even with the current version (v1.11.2). I am preparing a PR for issue #1596, which solves even this problem. So I expect that this problem will be solved not too far in the future ;-)
