Simply re-running the container seemingly fixed the bug, so it seems like a one-off, however is something you probably would like to be aware of.

I've been running into this issue relatively often as well. Did you happen to find a fix or workaround?

[jonwalz]

Also stuck by this.

[cosmtrek]

@ChrysmOre hi, could you give more details to help me reproduce it?

#677 fixed
