plugins: Wrong complierOptions when tsconfig in cwd is extended from another tsconfig

For example:

{
  "extends": "../../tsconfig.base.json",
  "compilerOptions": {
    "rootDir": "./src",
    "outDir": "./dist",
    "declaration": false
  }
}

Seems that rollup-plugin-typescript does not try to resolve the base tsconfig, so that the compilerOptions is not extended.

About this issue

I’m going to reopen the issue and try to solve the failing use cases described here.

@shellscape This still a relevant problem!

That extended tsconfigs are not supported should be documented or fixed.

Thanks for all your hard work!
