What do these changes do?

Adds a test for the quoting inconsistency that I believe needs change. It is written such that the compiled module passes but setting YARL_NO_EXTENSIONS=1 fails.

Submitting without the desired change to verify CI results. May or may not add actual content eventually.

Are there changes in behavior for the user?

No, but maybe there should be. Telling the user they are responsible about URL correctness is not particularly useful if the specific correctness properties are not enumerated.

Related issue number

Still roughly the same scenario, just moved from aio-libs/aiohttp#8088 where it was unnecessarily tested for, and thus failed on PyPy

Checklist

  • I think the code is well written
  • Unit tests for the changes exist
  • Documentation reflects the changes

We should really finish up #860 to catch the differences better...

If path is the only difference, could you parametrize the test?
