+Subject: [PATCH] Fix UI tests with dist-vendored dependencies
+
+There is already a workaround in `compiletest` to deal with custom
+`CARGO_HOME` using `-Zignore-directory-in-diagnostics-source-blocks={}`.
+A similar need exists when dependencies come from the local `vendor`
+directory, which distro builds often use, so now we ignore that too.
+
+Also, `issue-21763.rs` was normalizing `hashbrown-` paths, presumably
+expecting a version suffix, but the vendored path doesn't include the
+version. Now that matches `[\\/]hashbrown` instead.
