Interestingly, the effect I saw is that the window size is zero before

Do you use window scaling?
If you have window scaling the most likely explanation for your
observation is that the window is not really 0 but smaller than the
scaling factor.
I.e. assume the window is 7 bytes in size but you have a window scale
factor of 8.
Since 7/8 is 0, zero is what will be advertized.
