Missing threads when using thread group hints in Tracy 0.11.1 #883

I have been testing the thread group hint support in Tracy 0.11.1 and have noticed that it seems to somehow affect which threads are reported in the profiler app.

Steps:

  1. Register the main thread with Tracy (do not provide a thread group hint).
  2. Create 4 threads and set their name + thread group hint to value of 2.
  3. Create another group of 8 threads with their thread group hints set to the value of 1.
  4. Launch the application and the Tracy profiler on macOS.
  5. Capture using the Tracy profiler.

Expected outcome: All the four threads with the group hint 2 should be visible in the Tracy profiler and they should be listed close to each other, as should the 8 threads with the hint 1. The main thread should be listed at the top.

Actual outcome: About 50% of the time at least one of the threads in the same group are missing in the app.

Please see if #879 fixes this for you.
