Record type fail with circular reference error

[idoros]

TypeScript Version: 3.7.2 (and also nightly)

Search Terms: circularly references itself, Record circular reference

Code

type RecursiveTypeA = Record<number, RecursiveTypeA> // error: Type alias 'RecursiveTypeA' circularly references itself.

type RecursiveTypeB = RecursiveTypeB[] // works fine

type RecursiveTypeC = { [index: number]: RecursiveTypeC } // works fine

Expected behavior:
Record type should work like the third example that defines an object with number keys to the recursive value (the key type is irrelevant).

Actual behavior:
Only the Record type fail with circular reference

Reading the original PR that introduced recursive type, I can see that this has already been discussed and is by design.
