[Bug]: esModuleInterop: true without allowSyntheticDefaultImports: true is not the same

[simonhaenisch]

Version

29.0.3

Steps to reproduce

Have a tsconfig.json with "esModuleInterop": true but without "allowSyntheticDefaultImports": true.

Expected behavior

Only having esModuleInterop enabled behaves exactly the same as having both options enabled, because the docs for esModuleInterop say:

Emit additional JavaScript to ease support for importing CommonJS modules. This enables allowSyntheticDefaultImports for type compatibility.

See more: https://www.typescriptlang.org/tsconfig#esModuleInterop

Actual behavior

It's not the same. I encountered an error (TS2589: Type instantiation is excessively deep and possibly infinite) in my IDE but not when running the tests. Once I added

"allowSyntheticDefaultImports": true

to tsconfig.json, I would see the same error during the test run as well.

Debug log

Don't have one

Additional context

No response
