taco-chat demo doesn't work when run by hand

[HerbCaudill]

The taco-chat demo is broken when I try to run it manually, but not when the Cypress tests run.

Steps to reproduce

1. Check out main (42cb906 as of writing)
2. pnpm install; pnpm build
3. Confirm that Cypress tests pass
   • pnpm dev:cy:taco
   • run e.g. invitations suite
4. Try to replicate the "Alice invites Bob" test:
   • pnpm dev:taco
   • Press "Invite members", "Invite", "Copy"
   • Show Bob's laptop
   • Press "Join team", paste invitation code, "Join"

What happens: Nothing

What should happen: Bob should join Alice's team, they should both see each other in the list of members, and they should both show a team graph that includes Bob's admission.

Update: On my machine running MacOS Sonoma 14, this happens in some browsers but not others.

Browser	Engine, Version	Demo works?
Firefox	Gecko, 125	✅
Safari	WebKit, 17	✅
Edge	Chromium, 124	❌
Opera	Chromium, 123	❌
Arc	Chromium, 124	❌
Chrome	Chromium, 124	❌
Chrome (Cypress)	Chromium, 124	✅

I am very confused by this.
