`"module": "nodenext"` no longer infers `"target": "esnext"` in v7.0.0-dev.20260206.1

Steps to reproduce

v7.0.0-dev.20260205.1 does not have this issue, but v7.0.0-dev.20260206.1 does.

tsconfig.json:

{ "compilerOptions": { "module": "nodenext" } }

TS:

new Set().difference;

Behavior with typescript@6.0

No errors

Behavior with tsgo

error TS2550: Property 'difference' does not exist on type 'Set<unknown>'. Do you need to change your target library? Try changing the 'lib' compiler option to 'esnext' or later.

Yes, this was changed to match microsoft/TypeScript#62198; the target is no longer dependent on module (which was also dependent on target, a cycle).

A later update will introduce ES2025 and that will become the default (microsoft/TypeScript#63046), which will include those types again.

(Your issue says you tested 6.0, but this should have also happened there this week.)

Ah, I must have unintentionally tested against 5.9 rather than 6. Thanks for clarifying!
