2 chars and more string length delimiter prevents from deleting (with backspace)

[dimagimburg]

reproduce:

• options: creditCard: true, delimiter: "--" (-- originally for me was two spaces but)
• type 1234 5678 (which turns into 1234--56789)
• backspace until you get stuck on the 1234-- and cannot delete any more

Fixed and released in v0.7.21
However, multiple length delimiter is just an experiment feature though.

Same issue is still reproducible while using multiple delimiters, such as, delimiters: [') '] or delimiters: [' (', ') ']for a use case of phone numbers.
