Tracking issue for spurious rustdoc-gui tests

[jieyouxu]

Background

Some rustdoc-gui tests have been spuriously failing but the rate of which drastically increased over the last day or so.

Discussion: #t-infra > CI failure because `tests/rustdoc-gui/search-filter.goml`

Previous collection of spurious rustdoc-gui failures: #93784

Fix

Unclear at the moment, needs investigation.

Mitigations

• Temporarily disable 4 most-commonly-failing rustdoc-gui tests.
  • Remove the 4 failing tests from rustdoc-gui #152194
  • We should not forget to revert if properly fixed

Undoing mitigations

If underlying causes are figured out and proper fixes are applied, we need to:

• Revert tests removed in Remove the 4 failing tests from rustdoc-gui #152194

Ops log

• Treeclose: Rollup of 11 pull requests #152185 -> Treeopen
• Rollup w/ temp disable: Rollup of 4 pull requests #152200
