This can be recreated with current Wireshark (4.0.4) and a capture made with a icmp capture filter with a pause between pings to a remote site.
I'm not sure if this is an Enhancement Request or a bug. I couldn't find an existing issue (open or closed) related to this. Feel free to open a new issue on the Wireshark Gitlab issues page. Include which of the results is your preference if it were to be implemented.
I would have expected that if a given 1 sec chunk contained no data I would either get an empty .pcapng file for the given time period or I would get no .pcapng at all. I could live with either of these x2 scenarios.
