Research direction

Start by locating the isBrowserEnvironment definition and reproduce the issue with the strict-mode browser example in the report. Check the surrounding tests or browser-focused entry points before changing the detection logic. Done means the value is true in a browser even when the code runs in strict mode, with a regression test covering that example.
