isLevelEnabled not working in v9.3.1 and v9.4.0.

I have a sandbox where you can see this happening. https://codesandbox.io/p/sandbox/empty-leftpad-s52j5r

I'm using v9.3.1 and I swear this function was working a few weeks ago, I was working on something else and it suddenly doesn't work anymore. Using it like so.

const logger2 = pino();

  if (logger2.isLevelEnabled('debug')) {
   ....
    }

it fails at the function.

My understanding is this impact the browser build of pino
