Guillaume Gomez fe307c5452 Rollup merge of #150816 - method-anchor, r=camelid
Fix trait method anchor disappearing before user can click on it

A good example of this bug is going to https://doc.rust-lang.org/nightly/nightly-rustc/rustc_hir_analysis/collect/struct.ItemCtxt.html#impl-HirTyLowerer%3C'tcx%3E-for-ItemCtxt%3C'tcx%3E, and then try to click on the `§` anchor of the `tcx` method.

The solution to this bug is to simply "glue" the anchor to the method, so when the mouse cursor moves to it, there is no gap between the two, preventing the anchor to disappear (hopefully this explanation doesn't make sense only to me ^^').

First commit fixes the bug by expanding the anchor size.
Second commit is a small clean-up of the GUI test.
Third commit actually adds the GUI regression test.

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.
