Pixel 3 randomly disconnects with WPA 3

I have multiple devices on a single Netgear R7800 and the Pixel 3 is the only device I see that is randomly disconnecting multiple times a day. I see about a dozen disconnects at random times. Other devices include phones (Galaxy S8, iPhone 8) and non-phones (Home Theater, Chromecast).

The default logs on both OpenWRT and Android do not show a reason for these disconnects. I'll post the logs from each device.

OpenWRT 19.07.02 (started with enabling WPA3 with 19.07-rc*)
Pixel 3 Android 10 March 2020 update

Is there any logging change to either device to see more output?

The issue is not WPA 3 related as I thought it was. I had upgrading to both 19.07 and switched to WPA3 at the same time so I was making a poor assumption. Downgrading to WPA 2 didn't help and disconnects continued. Switching to the CT-HTT firmware didn't help. Switching to the very latest CT-HTT firmware from upstream didn't help.

I have narrowed it down to the CT driver and firmware.

Switching back to 'ath10k' and stock firmware has stopped the random disconnects. The Pixel 3 is now maintaining a solid connection. Every other device is also working as expected.

Was the switch to the CT driver and firmware premature? 802.11r doesn't work out of the box and some devices have issues maintaining connections.
