No confirmation received when running a Next.js dApp in production mode

[lgaroche]

Description
When running a dApp with Next.js 13 in development mode (with a local server and hot reload), contract interactions with Taquito work just fine. However, if the project is built for production, and served either locally or on Vercel, contract interactions never receive a confirmation. Instead, it ends up with the exception Error: Confirmation polling timed out being thrown.

Steps To Reproduce

1. Clone the simple reproduction repository (copy of the react example): https://github.com/lgaroche/taquito-next-issue
2. Run in development mode (see the README): contract interactions are fine
3. Build for production and start a local server: contract interactions fail

Expected behavior
There should be no behavior difference between dev and prod builds. I'm not sure whether the issue is on Next or Taquito side, but there's something odd going on with this specific scenario.

Hey, after trying a few things it turns out that disabling swcMinify in the next.config.js fixes the issue.

Looking at this discussion, it could be an issue with SWC.
