[Bug] Methods returned in object by function improperly indented when using 'return'

[KaKi87]

• Input code: KaKi87/puppeteer-helpers/mod.js
• Output documentation: KaKi87/puppeteer-helpers/DOCUMENTATION.md
• Expected: methods returned by page.js & userPreferences.js's exported functions are correctly indented like methods returned by browser.js's exported function
• Actual: the formers aren't (using => return {}) while the latter is (using => ({}))
• What version of documentation.js are you using?: 13.2.5
• How are you running documentation.js (on the CLI, Node.js API, Grunt, other?): CLI

Thanks
