tsconfig seems to ignore lib option

[waterplea]

Hi there.

I've created an Angular stackblitz and wanted to use Array.prototype.includes method, but even though blitz gets created with es2018 in lib, even changing target to es2018 doesn't help, TypeScript complains about includes not being available for arrays. It compiles, but the error message is there :(

Hey @waterplea! This is a good find- we might not be respecting the lib field right now (I'm not sure though :). Looping in @apai4 @KwintenP here who should have a better idea + deploy a fix!

I tried to do essentially the same thing with String.prototype.trimStart(), adding the appropriate lib and target values, except mine won't compile...
