Observed via CI, have yet to reproduce locally, assume it is intermittent.

Hi @crandles @jranson
I’d like to ask whether this issue is still available.

From time to time, I also encounter additional data races during tests, again within the ObjectProxy and DeltaProxy components. Because of this, I’m very interested in contributing if the issue is still open, I’d be happy to help.

Thanks!

[crandles]

I have not resolved this (or observed this again), would welcome the help.

Feel free to assign this issue to yourself.
