Min_max integration 'blipping'

Has anyone noticed this?

In the pic below, the blue line is a template sensor showing the min temperature from a group of Hue motion sensors. The pink line is the same but using the min_max integration.

The min_max sensor regularly blips, but the template sensor does not (i.e. it is not the motion sensor that’s blipping).
