Magic-Link Sveltekit example: Auth not working with slow connection

[philippviereck]

Bug report

Describe the bug

Using the sveltekit-magic-link example and throttling the connection in the chrome-devtools network tab, causes the login to quietly fail. Nothing happens, you're stuck on the loading animation from the example (/logging-in does not redirect to /dashboard) . Both slow 3G and fast 3G cause this.

To Reproduce

See above

Expected behavior

Login should work (even with slow connection)

System information

• OS: macOS
• Browser: Chrome
• Version of supabase-js: 1.35.6, "@supabase/auth-helpers-svelte": "0.4.5", "@supabase/auth-helpers-sveltekit": "0.6.8",
• Version of Node.js: v18.5.0

Additional context

I was not able to find the cause, but from observing the network calls one can notice that the /callback endpoint does not get called when using one of the throttled network speeds.

I'm unable to replicate this, you can see from my video below that everything loads on Regular 3G speed.
