New issue by rubin55 on void-packages repository

https://github.com/void-linux/void-packages/issues/40941

Description:
### Is this a new report?

Yes

### System Info

Void 6.0.10_1 x86_64 AuthenticAMD uptodate rrmFFFF

### Package(s) Affected

python3-lxml-4.9.0_1

### Does a report exist for this bug with the project's home (upstream) and/or another distro?

_No response_

### Expected behaviour

I install python3-lxml. Python3-lxml contains lxml/cssselect.py. When that is used, it in turn depends on python3-cssselect. I expect python3-lxml to correctly depend on python3-cssselect.

### Actual behaviour

[rubin@THINK lessfilter-pygmentize (master)]$ python main.py 
Traceback (most recent call last):
  File "/usr/lib/python3.11/site-packages/lxml/cssselect.py", line 13, in <module>
    import cssselect as external_cssselect
ModuleNotFoundError: No module named 'cssselect'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/home/rubin/Syncthing/Source/Other/lessfilter-pygmentize/main.py", line 8, in <module>
    from lxml.cssselect import CSSSelector
  File "/usr/lib/python3.11/site-packages/lxml/cssselect.py", line 15, in <module>
    raise ImportError(
