HA untracked comsumption is negative when the dishwasher runs

Wondering if anyone is seeing this as well, or if @astrandb may have a reason for this.

I have a G7660 dishwasher and in the Energy page, sometimes (not each time), when the dishwasher runs, I seem to get a negative "Untracked consumption".
The Untracked consumption is a new feature in HA 2024.8 (I think), I'm not sure if this is due to the way history is collected and skews happen, might even be a HA bug.

The graph shows up like this (where dark blue is the dishwasher).

There seems to be other people reporting this at home-assistant/core#125362 so possibly not related to this integration.

So I removed the dishwasher sensor from the Energy dashboard and the negative untracked values are gone.

I assume since the dishwasher sensor is exposing delayed data from Miele, that untracked consumption calculation has a surplus of energy when the statistics are calculated?
