Most of the YaKeIc I've ever worked with have this issue. Anytime you use ALC to control the power output there is a chance that that can happen if you are turning the power way down. When the rig is first keyed, there is a window before the ALC voltage is set properly that can allow this. It may be only milliseconds but with solid state devices, that could be all it takes.
I think this might be product specific, as ! never experienced this with any Brand-I or Brand-K & only with one Brand-Y product I have had or used over the years.
On that particular Brand-Y product, there is overshoot only when reducing power from the front panel control - not when the rear panel spigot is pulled negative - the exact opposite of what is mentioned above.
Probably best to check, as Terry says that little overshoot can damage - or if one of those rigs were driving something like a KPA500, spit out a bit of splatter that isn't nice.
