The data should be there but I think there may be limits on how much
the DB returns. Anyway, querying directly - looks like until ~june
there was something missing in the kconfig so the test was skipping.
But here is a June 1st run which passes:

https://netdev.bots.linux.dev/logview.html?f=/logs/hwksft/CX7-dbg/results/672642/test-outputs/35-pp-alloc-fail-py/stdout

so either it was running and not crashing for all of june...
or our crash tracking was broken in June :)
