Running an individual test by clicking Run Test does not respect the rust-analyzer.cargo.noDefaultFeatures setting.
In this minimal reproducible example, in .vscode/settings.json, default features have been turned off and the "blue" feature has been enabled. When running the test, the command executed is:
cargo test \
--package mre-cargo-test-default-features \
--lib \
--features blue \
-- \
tests::fails_with_default_features \
--exact \
--nocapture
i.e. it is respecting the "rust-analyzer.cargo.features": ["blue"], but not "rust-analyzer.cargo.noDefaultFeatures": true, and the test fails. Interestingly the code guarded by #[cfg(feature = "red")] is greyed out before clicking Run Test.

Research direction
Reproduce the issue using the linked minimal example and its .vscode/settings.json, then run an individual test through VS Code's Run Test action. Compare the generated cargo test command with the configured noDefaultFeatures and features settings. Done means the command also disables default features and the test behaves accordingly.
