Instructions to replicate

Current state

• cd ./before, pnpm i, pnpm dev
• open two windows of localhost:5173 and open RQ devtools
• invalidation across tabs will work
• hide the query in one tab, see in devtools that the query is removed in both tabs - invalidation across tabs no longer works
• show the query again, invalidation across tabs will still be broken even though the query has an observer in both tabs again

My (bad) fix

• cd ./after, pnpm i, pnpm dev
• same as above, but the query will now no longer be removed from the tab that needs it, and invalidation will continue to work across tabs
• see diff: https://github.com/c-ehrlich/broadcast-invalidation-demo/commit/e2133b9bb01876d31d9b259933b212002becd705 (the initial version of broadcast-query-client is just copy pasted from @tanstack/[email protected])
