bridge-pool-assignment seems to often miss all webtunnel bridges

it seems most bridge-pool-assignment on collector contains no webtunnel bridges, despite such bridging existing and seemingly working.

Between 2023-12-11-00-20-28 and 2023-12-13-23-42-31, 144 files have been generated, only 3 of which containing webtunnel bridges (2023-12-11-22-50-28, 2023-12-12-05-42-32 and 2023-12-11-22-20-28, each containing 46 webtunnel bridges). It seems impossible that the reason is 46 bridges being alive for one period, and dead for every other, all in sync, so there is definitely some bug somewhere.

I haven't (yet) check further in the past to know if it was always like that, or when it started. see below
