Please describe your bug.

I'm using the AmplifyUI library within a server-side rendered Angular application.
I'm seeing a constant memory increase on the machines running the server code until they crash
FATAL ERROR: Reached heap limit Allocation failed - JavaScript heap out of memory.

After some quick fiddling with the Chrome memory profiler, I strongly suspect something in the amplify-related packages to trigger the issue.
Please note that I'm not very proficient with heap snapshots interpretation.

What's the expected behaviour?

No memory leak

Help us reproduce the bug!

I've created a repository that reproduces the bug https://github.com/QuentinFchx/amplify-leak

ng build
node --inspect dist/amplify-leak/server/server.mjs

Open chrome://inspect
Go to localhost:4000 (refresh 1-2 times to warm the server)
Take a heap snapshot
curl http://localhost:4000\?\[1-100\] (perform 100 requests)
Take another heap snapshot

-> The memory constantly increases

Please note that :

• I disabled the pre-rendering "prerender": false
• The leak does not happen if I don't initialize the AuthenticatorService (remove the line private authenticator = inject(AuthenticatorService);)
