This is something i have been investigating and found that it is reproducible.
I'm just reporting this as an issue for the devs to look at when they possibly have the time
Two ways to reproduce.
After placing a rod in the rest on a boat, then fishing from land, the rod will whip up when picking up causing the line to scream out the reel and wear on the friction brake.
when fishing with a much longer rod like a telescopic and setting it on a rod rest the other shorter rods will whip up violently.
The vid shows the first way to reproduce. Sorry for potato quality - using non-gaming laptop.
Beginning of vid is normal behavior, after returning from the boat listen for drag and notice the rod tip moves more.
