According to the precedence rules in disable.js, when INSTANA_TRACING_DISABLE is set to 'false', it takes precedence over INSTANA_TRACING_DISABLE_INSTRUMENTATIONS and INSTANA_TRACING_DISABLE_GROUPS, preventing granular disable configurations from working in tests. This caused logging integration tests to fail when trying to disable specific instrumentations using INSTANA_TRACING_DISABLE_INSTRUMENTATIONS or INSTANA_TRACING_DISABLE_GROUPS.
