dayjs("02-29") return “2001-03-01”

Describe the bug In chrome and nodejs, dayjs("02-29") return “2001-03-01”.

Expected behavior I think "02-29" should be a invalid input. In firefox, this cause a error "Invalid Date". It's OK. In chrome, the dafault year "2001" makes it even worse. There is no "2001-02-29", but chrome/v8 makes it to be "2001-03-01". It's certainly wrong. (Maybe also a bug to v8.)

I have observed similar issue. Sending "2/31" is converting it to "3/2". Ideally it should be an invalid input and should throw validation error.
