Ref. https://bugs.chromium.org/p/chromium/issues/detail?id=1473980

What steps will reproduce the problem?

1. Visit https://helia-identify.on.fleek.co/
2. Open the console
3. Wait a minute or two

What is the expected result?

• No uncatchable WebTransport errors or warnings should appear in the console
• 👉 We should be able to detect when we have too many pending WebTransport sessions and close them
• 👉 We should be able to recover from this state and begin opening WebTransport sessions again

What happens instead?

A warning appears in the console: WebTransport session establishment failed. Too many pending WebTransport sessions (64)

All subsequent attempts to open a WebTransport session on any server fail with "WebTransportError: Connection lost"
