In this test we try to instantiate a Worker target for all the parent process workers:
https://searchfox.org/mozilla-central/rev/169bf38e150667afac81ab73ef8b5ace8f1dfa8d/devtools/client/framework/test/browser_target_parents.js#103-104

  for (const workerDescriptorFront of workers) {
    const targetFront = await workerDescriptorFront.getTarget();

But we fail over there with an exception:
https://searchfox.org/mozilla-central/rev/169bf38e150667afac81ab73ef8b5ace8f1dfa8d/devtools/server/connectors/worker-connector.js#36

 dbg.initialize("resource://devtools/server/startup/worker.js");

listWorkers methods may try to ignore such problematic worker. I imagine the worker is being destroyed.
Or it can be a race condition, and the test should probably accept exceptions when calling getTarget.

Hi Alexandre! Can you please take another look at this?
Thank you!

It isn't clear why the isDestroyed check isn't enough.
(Note that target and worker are the same object for workers)
But let's ignore workers with null names.
