Best reviewed commit-by-commit. I am pushing commits from my local branch as I am personally reviewing them for a first pass.

Part of #133895

Methodology:

  1. Refer to the previously written tests/ui/SUMMARY.md
  2. Find an appropriate category for the test, using the original issue thread and the test contents.
  3. Add the issue URL at the bottom (not at the top, as that would mess up stderr line numbers)
  4. Rename the tests to make their purpose clearer

The URL addition at the end, as well as moving around the auxiliary files and editing the stderr files with the new filename, were done using a Python script.

Tidy is going to get really mad at me due to its exclusions, this will be fixed at the end.

Inspired by the methodology that @Kivooeo was using.
