sniff does not terminate on timeout

Brief description

OS Debian 12, scapy v.2.6.1 The timeout parameter does not work when capturing packets: sniff(iface = interface, filter=“port 9999”, count = 1, timeout = 10) If there are no packets to capture, sniff should terminate after 10 seconds, but it does not - the program hangs.
