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.

[rustdoc] If line number setting is disabled, do not make line numbers take space
While working on https://github.com/rust-lang/rust/pull/150395, I realized that when enabled then disabled the "show line numbers" setting, instead of looking like initially:
<img width="904" height="148" alt="Screenshot From 2025-12-26 16-51-44" src="https://github.com/user-attachments/assets/a24df2f2-61be-4db5-b60f-519b35425fd2" />
The "space" taken by line numbers was still there:
<img width="904" height="148" alt="Screenshot From 2025-12-26 16-51-41" src="https://github.com/user-attachments/assets/b44af75d-52a4-4401-98e4-602b16bf6b9b" />
This PR fixes it.
First commit cleans up the `utils.goml` file a bit, I think I'll do more cleanup because switching the settings without reloading the page should make GUI tests a bit faster.
r? `@yotamofek`
add test against crashing with --html-after-content file
correctly add --html-after-content to env not args
formatting fix for rustdoc-call-locations-after-content/rmake.rs
Use local crate source file as default span in `render_call_locations`
- avoids unwrapping the first file added to the source map as a local file in
`href_from_span`
move test to tests/rustdoc-gui, rename to scrape_examples_ice
test link is correct
use rustdocflags, rename path in example, track lock file
factor out duplicate function calls
use compile-flags to make sure the after.html file is actually included in the rustdoc call
fix goml go-to path
increment assert-count in sidebar-source-code.goml
adjust crate-search width in search-result-display.goml
renamed Bar in scrape_examples_ice test
make crate name shorter ..
When this fails, you get output that looks like:
/home/user/rust/tests/rustdoc-gui/search-result-impl-disambiguation.goml search-result-impl-disambiguation... FAILED
[ERROR] `tests/rustdoc-gui/utils.goml` around line 49
from `tests/rustdoc-gui/search-result-impl-disambiguation.goml` line 25: JS errors occurred: Event: Event
Making the error message more informative requires patching browser-ui-test.
stuff like "clicking the settings menu closes the mobile sidebar"
is now impossible for users to observe, since the mobile sidebar
will always cover the settings menu due to being full-width,
which is good because that behavior is also now impossible for
our testing framework to observe.
