@gregberge the results when using ES2024 are inconsistent. I ran the test more than 100 times with a script, and up to 5% of the runs failed (because shiki return console. instead of console).

However, when switching to ES2018 (as recommended for maximum compatibility in Shiki’s documentation), the tests run significantly faster (200ms instead of 700ms), and I can no longer reproduce the 5% failure.
