Can anyone confirm a bug in Android/Jellybean/Nexus 7?

I have a visited an internal IP address and was able to enter the address quite happily, the IP address is now in the history. (say 192.168.0.1)

Now I try to visit another internal address (say 192.168.0.2) - each time I press a digit, it highlights the "cached" entry and the numbers disappear from the keyboard and I have to re-enable numbers only for them to disappear again when I reach the next number. Kinda makes entering in internal ip addresses a pain in the ass.
