A lot of "WARN reconnecting to bitcoind: Error: Connection error: disconnected from daemon while receiving" in recent versions

[tsjk]

I upgraded from e11cd56 to f87e908 and now see a a lot of
WARN reconnecting to bitcoind: Error: Connection error: disconnected from daemon while receiving.
I've previously also tried a dca8c59, which seems to have the same problem. So, something changed between June and October.
My elementsd is running on the same host, and both daemons run in podman containers. electrs is started as
electrs -vv --timestamp --db-dir /data/electrs --network liquid --daemon-dir /data/elementsd --daemon-rpc-addr host.containers.internal:<port> --cookie <auth> --electrum-rpc-addr <addr> --monitoring-addr <addr> --http-addr <addr> --address-search --index-unspendables --utxos-limit 131072 --electrum-txs-limit 131072
