Backspace on CVC field not working after 4 digits on Firefox

[kofi1995]

Hello,
Thanks for such a wonderful credit card validation plugin. Everything works great as expected but there is a little problem.
After entering 4 digits in the CSC field, the backspace no longer functions on Firefox. The problem is not seen in Chrome or Safari.
NB: I am using the latest versions of all the mentioned browsers.
