This is a bit surprising that broken breakpoints are stored as the frontend seems to try to do a couple of assertions: https://searchfox.org/mozilla-central/rev/c0fc8c4852e927b0ae75d893d35772b8c60ee06b/devtools/client/debugger/src/utils/breakpoint/index.js#84-106 But at least, now, we start using same assertions in both sides.
