Server perpetually restarts after rebuilding documentation

[JulianOrteil]

Describe the bug

context/problem
Launching sphinx-autobuild from tox (in conjunction with tox-conda) results in the server continuously relaunching. Specifying
--no-initial results in the server launching as expected until it detects a change and rebuilds the documentation, then this issue persists again. Also, CTRL+C is not responsive, I have to kill the terminal to quit this issue.

expectation
This not to occur.

Reproduce the bug

1. Setup and create an Anaconda environment, or at least have the program installed and on PATH
2. Install tox and tox-conda: pip install tox tox-conda
3. Create a tox.ini file with something similar to the following:

[testenv:autodocs]
description =
    Invoke sphinx-autobuild to hot reload docs changes
deps =
    sphinx>=3.2.1
    furo
    sphinx-copybutton
    sphinx-autobuild
commands =
    # Add --no-initial to see that described behavior
    sphinx-autobuild docs docs/_build/html

4. Launch with tox -e autodocs

List your environment

Python: 3.9.12
Windows 10
Anaconda env, likely not necessary
Other tools, see above
