Description: inspector/runtime/getDisplayableProperties.html The first failure I saw on the dashboard was on 8/24/2022 at 253764@main. The regression happened in the 253746@main-253797@main range, but I could not repro 253762@main; due to the lack of spades in that range. Commit 253762@main modified the way StorageNamespace is handled, which appears to have introduced the flaky crash. REPRODUCTION STEPS I can reproduce this on 253797@main but cannot reproduce it on 253746@main or earlier.
