AFAIK that advice was changed due to problems like what OP has described. The PoE and PoE+ HATs product briefs both now say they should be the sole power source.When I asked about dual powering for the 3B+ I was told that it was safe to have the PoE HAT connected while using USB power, and USB power could remain connected while powered by the PoE HAT
When the Raspberry Pi PoE HAT is connected to your Raspberry Pi, your Raspberry Pi should only be powered through the ethernet cable. Do not use any additional method to power the Raspberry Pi
