Problem & expected behavior (under 200 words)
An es modules imported by a tsx transformed file will be evaluated in sloppy/strict mode depending on the module type of the importing file, which should have no effect. A file parsed and evaluated as esm should always be strict.
When running tsx index.ts, we get isStrict: false which is incorrect. tsx index.mts or node index.mjs both output isStrict: true as expected.
For some reason a dynamic import does not exhibit the same problem.
