--reload-exclude cannot recursively ignore directories with '**' glob; changes outside --reload-dir trigger reload

[AntiSol]

Using uvicorn 0.32.1 (installed via pip) and python 3.9.18, and the attached directory structure (zipfile: uvicorn_test.zip), it seems that uvicorn is:
a) not properly honouring globs including the '**' pattern and
b) not properly honouring --reload-dir

steps to reproduce:

1. extract zipfile into an empty dir, cd to that dir so that pwd is the root of the zip/project
2. python3 -m venv venv
3. . venv/bin/activate
4. pip install -r requirements.txt
5. uvicorn --host 0.0.0.0 --port 4242 --reload --reload-dir myapp --reload-dir mylib/ --reload-exclude 'infra/**' myapp.api.main:app
6. modify a file in a subdirectory of infra infra/ e.g with echo "changed" >> infra/packages/foo/bar/baz.py
7. observe issue: uvicorn reloads despite
   a) --reload-dir specifying only the 2 directories and
   b) --reload-exclude specifically excluding subdirectories of infra/ using the '**' glob pattern.
8. observe that chanegs to infra/a_file.py do not cause a reload - it seems that --reload-exclude works, but only one level deep.
9. Note that using --reload-exclude 'infra/**' causes a substantial delay at startup if there are many files in the directory (i.e it seems to be enumerating all the files, but not properly excluding them)
10. quit uvicorn and restart it with uvicorn --host 0.0.0.0 --port 4242 --reload --reload-exclude 'infra/**' myapp.api.main:app (removing --reload-dir)
11. observe that the behaviour hasn't changed as far as I can tell - repeating step 6 will still trigger a reload

Output from uvicorn when I start it and modify the file in infra/packages/:

$ pwd 
/home/antisol/code/utest

$ uvicorn --host 0.0.0.0 --port 4242 --reload --reload-exclude 'infra/**' myapp.api.main:app

Another note: providing --reload-dir but not --reload gives the following output:
WARNING: Current configuration will not reload as not all conditions are met, please refer to documentation.

But I can't see anything about this in the documentation. I wouldn't expect to have to pass --reload if I'm passing --reload-dir, doesn't the one imply the other?
