[ERR_ASSERTION]: Fix objects must not be overlapped in a report.

[scott-lc]

Lint the following with the default sort-exports ESLint configuration:

export interface Alpha {
  apple: number;
}

export namespace Delta {
  export type Beta = string;
}

ESlint crashes with the following:

AssertionError [ERR_ASSERTION]: Fix objects must not be overlapped in a report.
  at mergeFixes (.../node_modules/eslint/lib/linter/report-translator.js:167:9)
  ...

This is not an issue with the namespace per se. The "cause" is due to the type Beta being alphabetically before the enclosing namespace Delta. Simply change the type Beta to something that comes after Delta alphabetically, or flip the sortDir to desc. For example, this lints fine.

export interface Alpha {
  apple: number;
}

export namespace Delta {
  export type Gamma = string;
}

The "overlap" that ESLint is complaining about is:

[
  { range: [ 45, 100 ], text: 'export type Beta = string;' },
  {
    range: [ 72, 98 ],
    text: 'export namespace Delta {\n  export type Beta = string;\n}'
  }
]
