What is the expected response to Window Probe packets

What is the expected behavior when Linux machine receives zero-window
probe packets? RFC says receiving client should respond with current
window size.

Does this mean that client MUST respond with a window update (if the
window size is still 0, say that it is 0, else give the current window
size.). Can client not responding to a window probe be considered as a
bug in Client's TCP/IP stack?

Thanks in advance
