Dayjs: customParseFormat plugin make some mistakes

[lyz810]

Describe the bug

import dayjs from 'dayjs';
import customParseFormat from 'dayjs/plugin/customParseFormat';
// this is right
console.log(dayjs('2020-01-01', 'YYYY-MM-DD', true).isValid());// true

// using customParseFormat plugin
dayjs.extend(customParseFormat);

// this is wrong, after customParseFormat plugin loaded
console.log(dayjs('2020-01-01', 'YYYY-MM-DD', true).isValid());// false

Expected behavior
The second console.log should print true as the first one.

Information

• Day.js Version 1.9.5
• OS: Mac OS X 10.15.7
• Browser : Chrome/86.0.4240.80
• Time zone: GMT +08:00

I've the same problem when I'm trying to use strict format:

This example should return true:

dayjs.extend(customParseFormat);
dayjs(
    '2020-11-08 19:34:39',
    'YYYY-MM-DD HH:mm:ss',
    true
  ).isValid() // false

Is this a bug or are we doing anything wrong?

I am actually noticing this is an issue between 1.9.4 and 1.9.5. I was seeing tests failing when we upgraded to 1.9.5 but they are not in 1.9.4.
