[rustdoc] Fix list margins Fixes https://github.com/rust-lang/rust/issues/131106. Fixes #131223. Follow-up of #130933. This PR changes the display as follow: the margin between list items is reduced by half to ensure that they visually still seem part of the same list, while also being bigger than previously which improves display for list items with more than one paragragh. Paragraphs also get they bottom margin reduced to a little bit less than the list items bottom margin for two reasons: 1. The list items keep having the biggest bottom margin which makes it better for coherency. 2. The paragraphs are still visually separated but they don't "overcome" the list. | before | after | |-|-| |  |  | Can be tested [here](https://rustdoc.crud.net/imperio/fix-list-margins/doc/test_docs/long_list/index.html). r? ``@notriddle``
The tests present here are used to test the generated HTML from rustdoc. The goal is to prevent unsound/unexpected GUI changes.
This is using the browser-ui-test framework to do so. It works as follows:
It wraps puppeteer to send commands to a web browser in order to navigate and test what's being currently displayed in the web page.
You can find more information and its documentation in its repository.
If you need to have more information on the tests run, you can use --test-args:
$ ./x.py test tests/rustdoc-gui --stage 1 --test-args --debug
If you don't want to run in headless mode (helpful to debug sometimes), you can use
--no-headless:
$ ./x.py test tests/rustdoc-gui --stage 1 --test-args --no-headless
To see the supported options, use --help.
