`lib` option in `tsconfig.json` is silently ignored

[nsbarsukov]

Description of Bug

Although tsconfig.json explicitly specifies "lib": ["ES2022"], StackBlitz still reports an error claiming that the target library does not include BigInt:

Error in src/app/app.ts (8:30)
Cannot find name 'BigInt'. 
Do you need to change your target library? 
Try changing the 'lib' compiler option to 'es2020' or later.

Since ES2022 already includes BigInt, this error should not occur. It appears that StackBlitz does not pick up the lib option from tsconfig.json.

Steps to Reproduce

Open https://stackblitz.com/edit/stackblitz-ignored-tsconfig-lib?file=src%2Fapp%2Fapp.ts,tsconfig.json%3AL20

Expected Behavior

StackBlitz should respect the lib option defined in tsconfig.json
