Pinecil V2: PD state with PD 3.1 chargers unstable, is this normal?

Observe the attached videos below. I'm using an Anker A2697 as a power supply and it works just fine at 28V. But I first noticed this in the detailed solder screen, it repeatedly blips from PD to QC briefly then back to PD.

Why is it doing this? It doesn't do this with an ordinary 12V PD charger (NITASA 30W) or a QC charger (GoalZero Yeti 1500X, actually a large power station but that's the only charger with a QC-only port I have around), the indicator just stays steady on PD or QC. I thought it was just a quirk of this particular charger so I borrowed a buddy's PD 3.1 charger (AOHI Magcube) and it does the exact same behavior.

Granted, this isn't an especially high priority issue since it doesn't seem to affect functionality, but it is puzzling. It happens regardless of PD settings or version I try.

The flickering in the PD menu is expected as for PPS or EPR you have to keep communicating all the time to say "I'm still alive" basically.

As of present the PD/QC in the debug menu is meant to be used for debugging so it doesn't filter state codes, so when the PD is re-negotiating it will not say PD.

I figured something like this might be the case but it's nice to have confirmation. Thanks for the fast reply!
