When using the 'Extend' option on an already registered domain, the input allows having blank year, and as a result the ETH gas price loader keeps loading infinitely

Another thing I just noticed is when I try to use + button on the blank input, it doesn’t increment the value by 1, but appends it in a manner of: 1 > 11 > 111 > 1111 > and so on.
