pfSense

If I press Enter in pftop filter field system redirects me to another page instead showing result in Output frame.

E.g.
for host 1.1.1.1 it shows

pfTop: Up State no entries (8), View: default, Order: bytes PR DIR SRC DEST STATE AGE EXP PKTS BYTES

for host 172.21.41.127 it shows

pfTop: Up State 1-2/2 (9), View: default, Order: bytes PR DIR SRC DEST STATE AGE EXP PKTS BYTES udp In 172.21.41.127:1194 172.21.41.138:1194 MULTIPLE:MULTIPLE 01:21:35 00:00:58 1285 169271 udp In 172.21.41.127:17500 172.21.41.255:17500 NO_TRAFFIC:SINGLE 00:16:39 00:00:22 34 6664

And for any wrong syntax request it shows

Invalid filter, check syntax
