no-magic-number regression starting with v20.1.0

[scottohara]

What version of ESLint are you using?
5.11.1

What version of TypeScript are you using?
3.1.1

What version of typescript-eslint-parser are you using?
Any version from 20.1.0 onwards

What code were you trying to parse?

{
  "parser": "typescript-eslint-parser",
  "rules": {
    "no-magic-numbers": "error"
  }
}

type Amount = 10 | -10;

const amount: Amount = 10;

What did you expect to happen?
No errors

What happened?
In [email protected], code passes with no errors.

With [email protected] onwards, the errors below occur:

1:15  error  No magic number: 10   no-magic-numbers
1:20  error  No magic number: -10  no-magic-numbers

The magic numbers that the rule is complaining about are the allowed values of the Typescript numeric literal type type Amount = 10 | -10.

I'm not aware of any way to define a numeric literal type that doesn't violate the magic numbers rule?
