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": {
    "indent": ["error", "tab", {"VariableDeclarator": {"const": 3}}]
  }
}

(in the code below, ^ represents a tab character)

interface Foo {
  a: number;
  b: number;
}

const foo: Foo = {
^ ^ ^ ^ a: 1,
^ ^ ^ ^ b: 2
^ ^ ^ },
^ ^ ^ bar = 1;

What did you expect to happen?
No errors

What happened?
In typescript-eslint-parser@20.0.0, code passes with no errors.

With typescript-eslint-parser@20.1.0 onwards, the errors below occur:

7:1  error  Expected indentation of 1 tab but found 4   indent
8:1  error  Expected indentation of 1 tab but found 4   indent
9:1  error  Expected indentation of 0 tabs but found 3  indent

The code can be modified like below to pass, but clearly this is not what the config intends:

const foo: Foo = {
  a: 1,
  b: 2
},
      bar = 1

Vanilla JS code without a type annotation passes as expected:

const foo = {
        a: 1,
		b: 2
      },
      bar = 1;
