Using the transport seems to break changing the log level

[TreeOfLearning]

It seems that using this transport prevents me from changing the pino default log level.

For example:

import pino from 'pino';

const logger = pino({
  transport: {
    targets: [
      {
        target: 'pino-pretty',
        options: { colorize: true },
      },
      {
        target: 'pino-opentelemetry-transport',
        options: {
          resourceAttributes: {
            'service.name': 'whatever',
          },
       },
     },
   ]
 }
});
logger.level = "trace";
logger.trace("trace");
logger.debug("debug");
logger.info("info");

Gives the output:
[20:51:12.705] INFO (2543437): info

Whereas this:

import pino from 'pino';

const logger = pino({
  transport: {
    targets: [
      {
        target: 'pino-pretty',
        options: { colorize: true },
      },
    /*  {
        target: 'pino-opentelemetry-transport',
        options: {
          resourceAttributes: {
            'service.name': 'whatever',
          },
       },
     }, */
   ]
 }
});
logger.level = "trace";
logger.trace("trace");
logger.debug("debug");
logger.info("info");

Gives the output:

[20:54:06.302] TRACE (2543472): trace
[20:54:06.303] DEBUG (2543472): debug
[20:54:06.303] INFO (2543472): info

And my otel collector only ever receives the info log when the transport enabled.

Am I missing something obvious?

Perhaps worth mentioning I am writing this in typescript and running via ts-node. Perhaps that's an issue?
