Because by the normal HWE policy [1] this got into Bionic rebuilds and it seems [2] the same is true for linux-azure kernel flavours. Could you check your logs if the kernel version changed between the old and the new runs? An alternative might be to rerun 18.11.2 to see if it drops as well, which might indicate that it wasn't 18.11.2 -> 18.11.3 but something else like the kernel. Not sure if that old kernel is ok, but you always can go back to what a version was released with. So in this case package linux-azure=4.15.0.1009.9 is still there and you could try 18.11.3 with that maybe? Let me know if you need help changing kernels there.
