 This is what I observed, from a simple end-user perspective. But actually,
 I didn't want to believe it and I never dared to create a ticket whenever
 I came across such an observation.

 As stated: my current practice is to reclassify my maps so that all
 legitimate 0's (and negative values) are replaced by some more or less
 meaningful positive integer. Can you confirm that this continues to make
 sense, if one wants to be on the safe side?
