Leaving this here for the future: E.g. this trace: https://sentry-javascript-sdks.sentry.io/performance/trace/24883c2fb15b4ea28ce5787afacc577b/ which comes from the canary tests (I think) shows the root cause, I believe. A bunch of "unrelated" (??) component renders are in the same trace, probably clobbering up the transactionName on the isolationScope, I guess... 🤔
